Guitar Reviews 4U - D'Addario Strings - Should I put heavy or light gauge strings on a guitar to get 'vintage sound'? We investigate....

 

Guitar Reviews 4U - D'Addario Strings - 

Should you put heavy or light gauge strings on a guitar to get 'vintage sound'? 

Here's a look at whether to go 'heavy' on string gauges and what this could do 

to your guitar to get the 'sound' and the potential damage to your guitar.

Most of my Stratocasters run with these 9-42 strings - 
a mix of standard 9 gauge Light top and 10 gauge bottom strings works great.
 D'Addario also make  9 gauge acoustic strings which I use on some acoustics


D'Addario show this great guide to string loading on the back of their
string packaging with the Brooklyn Bridge 'gauge' of string tension loading -
you can easily see just how much more load you create by going heavier! 

There has been a fad over recent years for some players wanting to recreate a more 'authentic' they perceive guitar sound, by using heavier gauge guitar strings. 

The reasoning often being that in the past, heavier gauge strings were only available and used then as standard fitment as the lighter string gauges were not then available.

Back in history, guitarists such as Eddie Cochran and James Burton used to get around this situation of heavy strings by using a light gauge Banjo string on the top E string and by discarding the low E string and installing the rest of the the strings A,D,G & B on the 6,5,4,3 & 2 positions with the 'ultra light' by the standards of the day string on the top E string position.

This allowed James Burton to get his famous sound. He could at least bend the top strings in his lead guitar work much easier.

On the Shadows tour in 2004, guitarist Hank B. Marvin of The Shadows used one of his Stratocasters strung with heavy gauge strings with a 13 gauge top to replicate his early 1959 Stratocaster sound for some of the old 1960's numbers played. His other stage Stratocasters on the tour were strung with more 'normal' modern 10 gauge strings.

Normally Hank might play a 10 top set, sometimes with a 52 bottom E in a 10-52 set rather than a 10-46 so he could get the heavier bass string sound of the old days without the need to fit the complete heavy gauge strings of a 13-56 set. This would allow the lighter '10 top' string unwound 3 strings to be used which are easier to play.

On this subject, some of the heavier sets now offer a wound 3rd like the early 1960's strings, Hank's early Stratocaster strings had the wound 3rd and some 'purists' use those to emulate the sound.

Going to heavy 13-56 range strings will appreciably load up the string tension on a guitar and in so doing, will put more strain on the structure of the guitar woods and the hardware. It does also make the guitar harder to play, there is more string tension to overcome when bending strings or using the trem arm.

I have used D'Addario strings since 1984 and I have also tried other string makes - Fender, Gibson, Ernie Ball, Rotosound and a host of others. Ernie Ball and D'Addario are really my primary choice now as they have a relatively low string 'pull' tension - I tend now to only really use D'Addario strings and Ernie Ball on a Buddy Holly style Stratocaster.

On a Stratocaster, changing makes even of the same string gauge range say 10-46 in both sets can cause problems, installing Fender 10-46 vintage strings for a tryout on a Stratocaster pulled my Trem block up some and led to me having to do some adjustment of the action.

When I put a new set of D'Addario 10-46's on a guitar that is new from a music shop and has the original 'from the factory' 10-46 strings on, the D'Addarios have less tension and sound much better. 

Over the last 40+ years I've tried different string makes and my conclusion is that the D'Addario strings are easy to play, have lower string tension and stay bright and in tune much better than others. Quality does not vary from set to set and I have only broken one top string in all the years playing them.

Back to the original question - heavy or light gauge? So, we consider the player wanting to replicate an artist's 'vintage' sound- they buy the guitar of their desire and decide to install the heavier gauge strings. 

Yes, you might get a louder sounding instrument with the higher mass strings, but you will find the strings harder to bend and perhaps harder to play, the guitar action will need adjustment to compensate for the string change.

The real issue for me as someone who has built and repaired guitars is the added load on the instrument, especially a vintage guitar made decades ago. The heavier load strings will put added loading on the structure of the guitar and may cause damage to the structure. Some old guitars were constructed using animal glue that can give out under heavy string loading. 

Older Gretsch guitars have tenon joint necks with screw location and these necks can move with age, so increasing the string gauge is not kind to them at all! It might have been ok when the guitar was new but some of these classics are now 60 years plus old and that has to be considered.

Personally after 40+ years of playing, I use a standard 9-42 set on most of my mainly Squier and Mexican Stratocasters and a 9-46 set on those I want a more vintage sound with the slightly heavier bottom strings such as a custom shop Maple neck 1959. My Tokai guitars have 9's on now a couple of 1983 TST 50's and a 2014 Goldstar Sound TST50. 

I use 10-46 universally on my Gretsch guitars - although the 5420's now come new with 11 gauge sets fitted, I usually swap those right away in any case and often as I install a Tunamatic roller saddle bridge and often swap the B60 Bigsby for a B6C 'V' style unit - all of which improves the sound and tuning stability greatly.

For acoustics, on acoustic 12 strings I use a 9 gauge set, on standard 6 string acoustic I have used the 9 gauge D'Addario strings and the 10 gauge set - the 9 gauge is a lighter string with less volume but is kinder to guitars I play less frequently. The 9's on a six string do have less volume but it is a trade off and I use them at home only. My Gretsch Rancher from 2013 has 9's on and sounds and plays very nicely. One of the best guitars for playability and sound.

To compensate for 'vintage' string sound you can if you use an amplifier modeller and a mixer as I do a lot, ramp the gain up (and presence if that is on your modeller) a touch and this will give a bit more 'alive' and 'loaded' vintage type sound.

An example of this vintage sound being found on The Shadows 'Man of Mystery' it is a great recording from 1960 and Hank's 1959 Stratocaster has the original heavy strings on, into a Vox AC15 and it really sounds fabulous.

Modern technology can to an extent be used to simulate the 'heavier' string gauge and that would be my route to follow rather than load up your instrument with strings that are more difficult to play and could also cause problems for the guitar structure.

Guitar Reviews 4U the Vox Tonelab ST Amplifier Modeller

 


Guitar Reviews 4U the Vox Tonelab ST Amplifier Modeller


The Vox ST is a compact version of the Tonelab EX
being introduced after the ceasing of the Tonelab LE board

The Tonelab concept as a separate modelling unit started with the Studio module and ended with the EX and ST modules. The EX being a slightly more functional module than the ST. It has easy connectivity to Apple's Garageband software.

As we have covered in our previous review on the Tonelab series modules, I've added this one on the EX as one has come my way at a price that seemed too good to pass up and allows me to have an example of each of the Tonelab units and one to review.

The Tonelab ST in all its glory that still retains the functionality of the
original Studio module but with patch selection and expression pedal.

The physical size of the unit is less than the earlier versions from the EX back

The Tonelab St has 11 Amplifier models, the Vox ones are referred to by name Vox AC 15 etc. and the other models made by Fender, Marshall etc are referred to by titles that suggest who makes them! 

After the amplifier model is selected, to the right is the tone controls and gain control, below and to the left a Pedal section where you can have Top Boost, Octaver and a range of features often found on small standalone module effects.

The Mod/Delay sweep switch covers the Chorus, Flanger, Delay and similar effects and to the right of that is a standalone Reverb section.

Completing this row is the Patch display and write buttons.

Unlike the previous Tonelab products, the ST doesn't have a 'Bank' system, in this case the ST has the first 49 patches as editable patches - as you would have on the other Tonelab products, but the remainder from 50 up to 99 are pre-set uneditable patches.

The patches are cued in by use of the up and down buttons on the last row at the base of the unit - here is also the Tuner which you activate by pressing both up and down buttons at the same time.

The ST is really a 'Light edition' of the EX, in that it has most of the functionality but a small footprint.

Why did I buy it? It is compact and I can edit plenty of patches for live playing in various musical styles and sounds which means I can go into my aux in on the Vox VT40 and use that as a PA and use the ST as a 'Brain' - having a clean and neutral channel set on the VT40 first.

It is a pity this set up wasn't put into an amplifier and the addition of bank patches would have been great. 

However, in the meantime Ipad interfaces into the new Vox VT40+ have meant that patch management can be done on the Ipad rather than on the amplifier, through Sound Editor set up.

Old School outputs now feature USB and the MIDI connections are no longer

The ST gives me the 'old school' flexibility and although I could use an EX for the same job, the ST will be fine for most situations.

Lastly, we have a volume pedal to the right of the main controls, this can also be assignable as an expression pedal. On the rear panel, the ST and EX have USB connection, so you can use these for connection to a computer for recording and the line switch options and output volume are handy for that and for going into a D.I. situation for live playing.

This is a nicely made unit and very functional, it has moved on from the LE by the adoption of MIDI outputs to USB which a bonus, you can get MIDI to USB conversion cables I believe but the USB connection is more modern.

Connecting to Garageband is easy, you can use the USB in to the computer, simply connect the uint and power on and in your Apple Menu>System Preferences>Sounds you can then assign the Tonelab to the Input source - be careful to have the volume down in Garageband before introducing the Tonelab as it can cause feedback if you are using a high gain input. Also set the output switch on the rear panel to 'Line.'

For my Garageband test track I used a clean sound Vox AC15 amplifier patch with the rear panel volume set at 12 o'clock position - so when the pedal is right down it does not overload the input. I tried it against an instrumental backing track and it sounded nice.

The EX really is the last of the Tonelab 'old school' units and is both a collector's item and a fully usable modeller. The lack of Bank facility is a downside but most of us will be able to get by!

Guitar Reviews 4U - The VOX DA5 - 5 Watt Practice Amplifier review

 


Guitar Reviews 4U - The VOX DA5 5W Practice Amplifier - 

Features a Mic and AUX input on the rear panel - ideal for the Beach!


The Vox DA5 - a Mini Vox amplifier that can be Mains 9v or AA powered 

The DA5 is a small and simple amplifier ideal for songwriting, recording or live busking, as it has a choice of power sources either a mains to 9v adaptor input (Mains current down to a 9v input into the unit) or AA Battery power (AA Batteries) for playing outdoors in the street, on the beach or in the garden. It features power output settings of 0.5w, 1.0 watt and 5 watts on a slider switch found on the back panel.

It is also a useful workshop amplifier to test guitars you've been working on too! 

The version shown above is in the 'classic' Vox look and style used since around 1960 that was applied to the early VOX AC30 with the Black Tolex and Diamond woven Speaker Grille cloth and Gold 'Vox' name badge.

What the DA5 can do is surprising, that given a few years ago a small guitar amplifier of this size would only feature Volume and Tone Controls with a Reverb if you were lucky. The DA5 moves that limitation on with a good array of Amplifier types and Effects on board.


Vox DA5 in alternative Red Tolex and with Stainless Steel pressed Grille -

Black Tolex is the usual finish, White, Red and Pink Tolex are limited run options


The other version of the DA5 is as found above with the metal grille cover, usually it is with a Black Tolex finish and pressed Grille of a style found on the VT 30 to VT 100 model modelling amplifiers. I wanted the classic old Vox look and chose that version, otherwise there is no difference to the controls.

The DA5 is a plug and play small amplifier which does not have any modelling features such as patches or banks, largely as it has not got the space for the digital controls for these on the top panel. On the top panel, you can find the Amplifier Model or type settings as your start point. 

Vox usually on their units and in their owner's manuals alludes to the trade names of amplifiers by cleverly using such names in such cases as 'Blues' to equate to a Marshall, ' 'Clean 1' and 'Clean 2' these usually are AC15 and AC30 type amplifiers, 'Crunch' a Hi-watt and 'Hi Gain' a Rectifier amplifier for this example. Those can vary according to the number and model being replicated.


The Top Panel gives you easy access to the controls


The Rear Panel has a Microphone and Aux in inputs

The rear panel houses the Microphone input (a 6.35mm mono), an aux in for your MP3 player and a Line / Phono output for headphones or a mixing desk. A slider switch allows you to attenuate power in 0.5, 1 and 5 watt outputs. So you can play along with your vocals too, there is no bluetooth on this model so you can't beam backing tracks to the unit, you have to physically connect them via a 3.5mm cable.

Playing the guitar through the DA5, you'll find the simple to use controls useful to get the sound you require quickly and easily. On the 5W setting, in a bedroom the DA5 is quite loud enough even at a low volume and is useful for playing along to DVD's on your TV.

Back to the controls, the amplifier settings are descriptive so you have a flavour of the sound by the description. On the top row are a Master Volume, Tone and Gain, so you can crank the amplifier there if required, used in conjunction with the rear switch if you want to achieve a driven sound at low volume output.

There are twelve effects which are quite usable and can be controlled from the Edit function control for in cases speed, depth or time depending on the effect chosen. There are no 'Bank' or 'Patch' settings to save these too but that's a trade off for the size of the unit.

The DA5 is a good small amplifier to have to hand for various jobs, as a portable play outside amplifier, a workshop guitar tester amplifier, or as a small studio or songwriting amplifier and also for playing along to music from the TV or a music centre.

Value for money is good, although the DA5 is not a current Vox product you can find them secondhand reasonably priced. Later Vox models of the DA5 concept with more features including a Tuner are the Mini GT2 and GT3 Amplifiers can also be found used.

My only issue with the DA 5 is the small length of lead on the mains adapter, however a replacement of the same mv rating with a longer lead is only around £10 so that is an easy fix.

Vox Tonelab Amplifier Modellers - Tonelab Studio, Tonelab SE, Tonelab LE, Tonelab EX - reviewed

 


Vox Tonelab Amplifier Modellers review


The requirement

In the early 2000's, Vox through their association with Korg brought the Tonelab amplifier modeller to the world of guitar players. It was a reaction to the introduction of the Line 6 POD Amplifier modeller which was very successful at the time.

The Vox Tonelab 'Brain' of the Studio unit was also built into two vintage looking Amplifiers the AD 60 VT and AD120 VT - giving the retro look of an old AC15 and AC30 but with more onboard functionality than those originals, like the AD 60 and 120 these were amplifiers that Vox has not bettered.

The Tonelab products featured control knobs which guitar players would instantly be at home with, rather than buttons and menus and sub menus that were found on effects rack modules of the time. Simplicity of operation and the tones were key!

Here's a  review of the various Vox Tonelab products I have owned.

The Tonelab Studio version

How it started - The Vox Tonelab Studio

In the late 90's I had a Line 6 POD and that was a great introduction to the new arena of Amplifier Modelling - and the POD was a game changer for live guitar and recording players, with good reproductions of classic amplifiers and effects in one red kidney bean shaped metal box. It could be used on stage or in the studio alike.

It suffered the drawback of the Tonelab Studio unit in that the Patches and Banks had to be manually selected which could be inconvenient in a playing situation.


The Vox Tonelab Studio rear panel

The Line 6 unit prompted other manufacturers to come up with their own type of modeller, Boss for one with their GT multiFX unit, Behringer with their product and so on. Vox as part of the Korg group were not to be left out nor were shy on using the technology and expertise of Korg's synth functionality - seen in their Triton and similar synths in this new area of guitar electronics. 


The Line 6 POD's shape was unique

Vox launched their Tonelab Studio, a standalone unit that could be used in music recording and  also in live playing, with sound patches arranged in banks of 4 x 24 Sets that could be edited, saved and renamed to your own preferences. 

The preset patches often were constructed and modelled to give you the same guitar and amplifier settings used on classic songs by well known performers. Being able to recall these quickly was a major advantage to players on stage. 

Vox's 96 patch palette was a great advance and sadly the VT series of amplifiers to follow after the AD60, had a mere 8 user patches. 

Apart from the Vox amplifiers featured on the Tonelab unit, the other amplifier models likely based on Fender, Mesa Boogie, Marshall and others were euphemistically named, so you could work out what they represented without having to give the actual name of the amplifier, property of other manufacturers! Once you heard the patch, you got the idea what it was alluding to!

For a performer, especially playing a broad range of music at weddings & functions, the Tonelab gave a quick way of having pre-defined amplifier and guitar effects sounds to hand without the need for changing settings and levels. A problem on darkly lit stages or where one song of a different style and perhaps volume segued into another was now solved by the pre-sets on the Tonelab.

The VC4 Foot Controller



The VC12 Foot Controller - as like the VC4 could be
used with the Tonelab Studio and the AD60 and 120 Amplifiers
The VC12 could store over 100 patches

There was one drawback on that original Tonelab was that it needed to be within reach of the player to effect the change of patches via the small buttons and it was not always convenient to break off playing to select a different patch. Or you would need an assistant to select the patches for you, remotely. This was true when you set a patch for accompaniment playing and then needed to switch to a patch with more gain for a lead solo. 

The introduction of the VC 4 and VC12 Foot controllers solved this issue. Both of these boards could be used with the Tonelab Studio and the AD series amplifiers, connecting to them via a CAT 5 Data cable connection. 

Both of these pedals are hard to find these days - I have VC12s as they offer greater functionality including the ability to back up the patches as I use them on my AD60 and 120's too.

With these, it was a case of using the foot switches to make your patch selection. This made the Studio a viable proposition for live stage work and a benefit in the studio too for volume control. 

The VC12 had 2 pedals one for volume (Outer) and the innermost one could be assigned as an expression pedal for Wah Wah effects for example, independent of the volume pedal as on the Tonelab SE version.

The Vox Tonelab SE - Stage Edition


The SE model added extra functions of patch & bank buttons and extra pedals

The Tonelab SE came about as the logical development of the Studio unit, the SE 'Stage Edition' gave you the the VC12 foot controller chassis amalgamating with the Studio 'Brain' of the Studio unit with the addition of a slightly increased functionality all in one place.

The AD60VT and 120VT Amplifiers

The AD120VT Amplifier and VC12 Foot Controller


The AD120VT Control panel - much like the Tonelab Studio and SE
in functionality and largely with rotary controls and few buttons

The AD60VT and AD120VT were a logical amplifier extension of the Tonelab Studio, the 60 was in the style of the old AC15 'TV cabinet' style amplifier, with a single 60 watt speaker and a rear attenuator rotary switch on the back panel giving various set outputs between 1 Watt and 60 Watts. The 120 had two speakers and the same rotary control.

This made these amplifiers ideal for home, studio and stage use. Built around 2000-2004, they were not USB equipped, being somewhere in that netherworld between old and modern connectivity! We have to remember that back then, MAC computers circa 2000 used SCSI as an interface before USB became the most used method of connection of devices. 

Although boards could be used to retrofit a USB socket board to old SCSI era 9600 type Mac computers. The Tonelab Studio and SE did have MIDI DIN Sockets on the rear panel which you could use with some sound cards of the time. This was the time when Cubase and Logic were the new recording studio programs for computer home studio recording.

The AD series amplifiers embodied the Tonelab concept with a reduced 32 patches, still enough for the majority of performers. However, the AD amplifier could also be used as a slave amplifier - on one patch just set it to 'flat' with tones set to mid positions and the Studio module then connected by audio left mono 6.35 (1/4") jack out to the input of the AD60 or 120, so you could use the greater patch selection of the SE via the amplifier as a 'driver'.

The Tonelab LE 

The Tonelab SE was a great success and Vox went onto replace that with a more functional and compact unit called the LE. The LE featured a 120 patch capacity over the 96 of the SE, the LE lost the inboard expression pedal of the VC12 and SE which was a reduction in weight too. 


The Tonelab LE rear panel view

The controls layout was simplified too for the LE but also some of the functions like the Reverb was expanded. Whereas the SE is ideally suited to classic vintage sounds, the expanded capabilities of the LE allow it to venture into more modern sounds too.

The rear panel features send and return 1/4" Jack sockets, Headphone 3.5mm stereo socket, 2 x MIDI Sockets, single 1/4" Jack socket input and left (Mono) and Right 1/4" sockets to a PA or mixing desk. An SPDIF optical socket on the rear panel is also fitted which connects to the G5 type Apple Macintosh.

The Tonelabs from LE backwards all use a din type lead connectable transformer.

Not one to rest on their success, Vox then introduced a smaller still pair of units to move forward from the LE:



The Tonelab ST top and rear views





The Tonelab EX - features on-board speakers

Last but not least are the later incarnations of the LE compact Tonelab un it, the ST and EX Amplifier modellers. 

The ST is the less well appointed and simpler unit but still a very versatile modeller compared to the EX. The EX has a pair of onboard small speakers mounted under the top plate between the 1 & 2 and the 3 & 4 Foot Switch buttons. 

The EX speakers are small but give you the sound of the patch when played without having to use headphones or connect to an amplifier. Both of these new limits now feature USB connectivity having moved on from DIN MIDI connections for a soundcard. 

All of these units differ depending on what you go for and indeed what you are looking for. I have owned them all and the EX is the only one I don't still have. Whichever one you go for the audio is superb, I purchased my Studio to play along to Shadows backing tracks and the sound is really close to the original recordings.

Due to the different features on the individual model types, not all the settings will be the same.

25 years on from the Line 6 POD and the Line 6 Spider Amplifier, these Vox units are still sought after, get one while they are still affordable and about.

Guitar Reviews 4U - Boss Dual Cube LX 10W Desktop Modelling Amplifier review

Guitar Reviews 4U - Boss Dual Cube LX 10W Desktop Modelling Amplifier review


The Boss Dual Cube LX 10W

Need a convenient small amplifier you can run an amplifier modeller on with flat response so you hear the modeller uncoloured by the amplifier?

I saw this Boss Cube unit and what appealed to me was the facility to be able to connect an amplifier modeller like a Vox Valvetronix SE and an Ipod to the Boss to use for playing against backing tracks at low volume at home. 

The top view of the controls layout -
note the typical Boss control knobs used here


In this 'flat response mode' (selectable as a position on the amplifier models control), the amplifier modeller would come through with the sound 'as played' and not influenced by the base amplifier tone controls or efffects. It means you can in most cases avoid using an external mixer as an input device before the Cube, for most playing along to tracks situations.

With an 8 AA Battery bay, you can take this onto the street to play or outside as a small PA, there is Bluetooth connectivity via an optional module so you can stream music to it. And with 2 small 5 watt speakers it should be loud enough not to annoy the neighbours!

The main inputs are stereo left and right 1/4 jacks so you can use the left as a mono only if using a guitar for example or both if the external effects unit has two outputs so you can get true stereo. 

The unit is very easy to use, with the benefit of Boss style pot knobs as you get on the famous guitar pedals, so the controls are easy to set without having to use push button menus. The only slight issue perhaps is there is no on-board tuner for the guitar, but if like me you'll use it for amplifying a modeller unit, chances are the modeller will have a tuner built in there, as my Vox units have.

The effects are good for a small unit and the amplifier types of which there are 9 on a rotary knob control include an acoustic guitar simulator, a Roland Jazz chorus amplifier, Fender Twin and a range of higher gain units are modelled. Plus the dedicated microphone and flat response as the last two settings on the rotary switch.

I have mainly used the Roland setting for guitar to do some song writing and the sound is good, it goes down low so you can play along without disturbing people and up to 5W so it is fairly loud for a room.

Its a very versatile unit and does just what I want and I think it is good value for money. I connected a Vox Tonelab SE to the Cube and it sounded good, which was the reason I purchased it for.


The rear panel with foot switch, USB & Blue tooth connection

(This stereo input section also allows you to use a mixer, if you want to change the tone of the modelling input device - rather than put say an Ipod into the aux input, you can output signal sound to a mixer and then bring that into the Cube - giving you more control over the tone.)

Besides that, the Dual Cube LX10W is a small programmable amplifier you can connect via USB to a computer for recording with 3 presets you can save per amplifier model. 

The Dual Cube LX offers many ways to play along with backing music from a mobile device or computer, via a stereo aux input, USB and i-CUBE Link Loopback, and an optional Bluetooth® adaptor. 

With the Phones/Rec jack and mic volume control, you can capture your voice with a headphones mic and send it to the USB and i-CUBE Link outputs along with your guitar sounds. You can also add the optional foot controllers for the sample Loop option.

Here are some great features of the Boss Dual Cube LX:

  • Ultra-portable stereo guitar amplifier with professional sound and features

  • Two custom-designed 4-inch speakers

  • 10-watt stereo power amp (5 watts x 2)

  • Eight newly developed guitar amp types plus one mic preamp type

  • Seven onboard effects with deep editing via the DUAL CUBE LX Editor app 

  • Stereo input mode with wide, immersive sound for modelers and stereo pedals

  • Three-band equalizer

  • Store amp and effects settings in 27 memories (3 memories for each amp type)

  • Powered via AC adaptor (included) or eight AA batteries 

  • Stereo line output with mic’d cab emulation

  • Phones/Rec jack with support for an inline headphones microphone

  • USB audio for direct recording and livestreaming 

  • Control jack for up to two external footswitches

  • i-CUBE Link/Aux In jack for audio playback

  • Selectable Loopback function for USB and i-CUBE Link/Aux In

  • Onboard looper (requires optional footswitch)

  • Connector for optional Bluetooth® Audio MIDI Dual Adaptor (BT-DUAL)

Optional accessories:
