Blues Junior Rebuild

This month I spent a couple of days rebuilding my poorly Fender Blues Junior with the chaps at Vyse Amps in Pinner, London. 

The amp has been my go-to combo for 8yrs, and being 12yrs old and seeing a lot of action, it has had a lot of heat cycles through the solder joints which is the root of the problems coming through. The power amp valves’ solder was beginning to crack, and the tracks on the PCB were lifting and ultimately breaking. 

The solution to this – which would become endemic throughout the rest of the amp in time – was to remove all of the original components, and replace with a new circuit built in an old-school ‘point-to-point’ fashion which would enable me to make modifications or replace any faulty components much more easily for the life of the amp. 

Since completely changing everything except the cabinet and reverb tank, the amp has taken on a different character, but is a beautiful alternative to the Blues Junior I knew and loved. It’s now got a Celestion G12H Anniversary Edition speaker, and in conjunction with the up-rated electronics is more articulate as a result. I’m still getting to know the amp, but can’t wait to see how it performs on gigs and shows as they come in! 
   

  

  

  

  

  

  

  

  

                      

                   

Assorted Jobs – Ibanez Switch Replacment, Overwater Setup, Tangelwood Fret Stone

It’s been another busy week here at Aylesbury Guitar Repair, with an interesting mixture of jobs required to be done.

The first was a rather sorry, 30yr old Tangelwood acoustic, whose frets were in appalling condition littered with dents from strings, bizarre diagonal ‘grazing’ and one or two frets with flattened edges under the high E string. Furthermore, the bridge saddle was so low that the guitar was more or less completely choking out around the 5th fret up, and as such was more or less unplayable!

The owner just wanted a basic setup, so the guitar could be played along the length of the neck – not the most demanding of requests on the face of it, although the work to get it there was fairly substantial!

I started by levelling the neck and fret-stoning and re-crowning the frets, then polished to a high shine.

Next, I set about cutting a new bridge saddle from a bone blank, only this one was about an extra third deeper than the original to get sufficient clearance, but with a friendly action to aid playing.

Once the new strings were added I checked the string spacing, action, the intonation, and once satisfied I polished the guitar to finish the job.

This is a completely different guitar from when it arrived, and was very fun to do. Delivering a like-new instrument is always a buzz for me, and I know there will be many hours of enjoyment as a result of the work that was carried out here.

The next guitar was an Ibanez whose pickup selector switch was malfunctioning – there was a spot between positions 1 & 2 where the guitar cut-out completely, and would often get stuck there mid-performance. This was clearly unideal, so a replacement was required.

The switching for this guitar is quite complex, utilising an OTAX VLX91 switch that has double the number of contacts available to create many interesting pickup combinations when using 4-conductor cable.

A a H-H equipped guitar, the sonic options for this guitar are very varied with the following…

1. Neck wired series
2. Neck wired parallel
3. Neck and bridge together
4. Inner coils
5. Bridge wired series

With this you can get some lovely warm tones, powerful ones (courtesy of the DiMarzio Evolution pickups) and single coil out-of-phase-type scooped ones.

The wiring was a little bit tricky in places – quite precise and fiddly – but the job was done first time and the owner is super happy with a more taut switch, minus the unwanted killswitch bonus!

Another job that took place today was a setup on an incredible Overwater bass. This is a custom-made instrument that needed thicker strings to accommodate the new owner’s preferences in feel. The action needed to go too, and this was helped by the increased gauge, and then the intonation needed some adjustment.

I typically find that 5-string basses are quite challenging to get perfect on the Low B, but the Hipshot bridge on this bass was fantastic and settled really well! Highly recommended.

What was interesting on this instrument was that the fretboard was so flat – there was minimal radius in the fretboard, but it was wonderfully playable!! An all-round beautiful instrument!

Ibanez RG3120, Assorted Basses and the Martin

So the Martin got finished beautifully – the action was so good that any electric guitar would be proud to bear it, and it really plays effortlessly.

I’ve since received some school basses that have a myriad of different issues, including missing jack sockets, missing pickguards and exposed wiring, and intonation issues. They need some serious love but I’m sure the results will make them a real joy to play in the end!

Next, this Ibanez walked in. It needed a fret stone, re-crown, setup and also needs it’s switch replacing as there’s a spot on it where the signal cuts out completely!

I started with the fret stone and re-crown so that I could batch some soldering together once I get the go-ahead on the basses.

The pits that were present in the frets came out really easily, and they polished up beautifully after lots of elbow grease! Once that was all done I set about lowering the action (came down by a 3rd so is now mega-low!) and now it’s so easy to play. Unreal, and so exciting! It’s a new guitar. One tweak of the intonation on the high E string and it was good to go!

Musicman Stingray and Martin Acoustic

Today is an exciting day at Aylesbury Guitar Repair.


(null)

This magnificent Musicman Stingray 5-string bass has wandered in and needed a little bit of attention.

This instruments are fantastic – great build quality and their technical appointments are top notch, too. Real player’s instruments!

This one needed the fretboard to be cleaned, new strings fitted and intonation sorted out, so that’s what I did! It’s come out beautifully!

Next on the list is this Martin acoustic.


(null)

This is another very special instrument – sounds incredible plugged in and plays nicely. The action needs to come down on this, and that will take place once I’ve fret-stoned and re-crowned the frets as there’s a bit of wear on them. I can’t wait to see how this one comes up!

Crafter Acoustic Setup

This little baby is amazing! It arrived with a reasonable action but it had room to come down and that’s exactly what I did.

The truss rod had room to be tightened to encourage the neck to straighten, and this helped me keep the action down across the length of the neck.

I took about 1.5mm off the base of the bridge saddle, sanded it smooth, replaced it and then checked the resulting action.

It came out wonderfully, measuring 1.5mm at the 12th fret. There’s no buzz whatsoever and it almost plays itself!

Fender USA Deluxe Jazz Bass

This was a lovely instrument to start the day with! She just needed a little attention to bring the action down a touch to make her easier to play.

The truss was already pretty taut, so straightening the neck further was tricky and I was naturally reluctant to push my luck!

Despite still having a some curvature (probably the right amount to be fair!) I set about lowering the bridge saddles.

Overall everything was able to come down by about a third, meaning there should be a marked difference in the feel of the bass when the player gets it back. I’m excited to see what they think!

Once the intonation was done, she got a good polishing and then back into the case to await collection. Done, done, onto the next one!

Gibson Les Paul Gold Top String Gauge Change

How classy is this guitar? I love the gold too finish on these guitars… So beautiful!

The client wanted to take this up from 10’s to 11’s, and originally had a set of Elixir strings, with the new ones being Ernie Ball Power Slinky.

During the process I stripped and polished the hardware on the guitar, which also enabled me to get under the pickguard – it’s like a new guitar!

Stringing this baby up was a real joy! The action is set super low, but she sings! The clean sound is lush on this… Mustn’t covet!

Freshman Acoustic and Aria Electric Setups

Well today has been an interesting day of setter-up-ering!

The Freshman acoustic already had a very low action – almost too low – so alongside cleaning the fretboard of all of the gunky deposits, I raised the treble side of the bridge in order to relieve the buzzing on the neck a fraction.

IMG_7154.JPG
The truss rod was pretty seized from a setup, so the neck had to stay as straight as it was, but this didn’t prove too problematic, and the guitar plays great – especially for an acoustic!

IMG_7155.JPG

The Aria guitar was a very different problem, as the jack plate needed bending into shape – for some reason it was very flat in it’s profile from new – so I needed to flex the guns!

First I need to de-solder the Jack socket, and saw through the threaded section of the socket because the nut holding the Jack plate in place wouldn’t come off! Quite extreme measures, but it needed doing.

Once that was done it was a simple job to bend the plate to match the curvature of the body of the guitar, a re-solder of a replacement chassis, then a straightforward set-up from there. This was a really lovely guitar to work on, and the action is much slicker now!

Classical Bridge Saddle and Nut Replacement

Today I completed a bridge and nut replacement on a classical guitar. The saddle in particular needed some work to become thin enough to match the slot on the bridge, but she was there after a little sanding and coaxing.

With a fresh set of strings, a polish and tune up she’s ready to go!

Replacing Reverb Tanks and Finishing the SG

Today has been another interesting day in the workshop! So far I’ve replaced a couple of reverb tanks in a couple of amps, and I’ve been able to finish the SG off.

I got the replacement tanks from Hot Rox Uk, and the service was quick and efficient. They’re competitive on pricing so it was a good experience dealing with them.

The tanks are direct replacements for a Fender Blues Junior and a Mesa Boogie Lonestar Special, although the later tank is made by TAD rather than Belton/Accutronics, which is the brand you’re most likely to find in many Marshall, Mesa and Fender Amps and many more besides.

There are notable differences in the construction of both tanks – the Belton appears to be more expensive to manufacture, so we’ll have to see if it translates to a better tone/experience with the customer.

The SG client opted to get a new set of Gibson Classic ’57 and Classic + ’57 pickups with shiny chrome covers. These differ only slightly from the previous pickups, but sound great now that they’re in the guitar. They sound bright to my ears, in comparison with ’57s in a Les Paul I’ve got, but still lovely and versatile and definitely better than the stock pickups these guitars come with. It’s been a real treat to work on this guitar, and I look forward to the next one!
