Guitar Repairs London: 1961 Guild M20 Acoustic



 

This lovely old Guild on the workbench is in need on a bit of TLC.

Seasick Steve M20 Full

It’s an M20 made in 1961. This model has been called the Nick Drake model because of the association with him during the 70s.

This particular guitar belongs to Seasick Steve. You may have seen him on the Jules Holland show or heard him on the Chris Evans Breakfast Show on Radio 2.

The guitar has got a few problems. The soundboard has a distortion at the edge of the sound-hole. Frets 1-5 are worn and there are some intonation issues.

Seasick Steve is in London for a limited time so the guitar has to be repaired and turned around very quickly.

 



 

Close inspection reveals a loose X brace on the bass side. This is causing the distortion in the soundboard at the sound-hole. The loose brace is glued, clamped up left to dry overnight.

The intonation issues  is caused by a badly fitting nut. Also it is not intonated correctly over the bridge saddle. These and discarded and a new bone nut and saddle are made and fitted.

A light redress of the frets is enough to take out the wear in the frets.

Soon the guitar is playing smoothly and sounding great.

Seasick Steve thinks so as well.

Electric Guitar Repair: 1968 Gibson Melody Maker



 

Luke Crowther from The Rifles dropped by the workshop a few days back. He was collecting his Gibson Melody Maker.

Melody Maker

On the Bench


This lovely old guitar was made in 1968 and has been cherished by Luke for many years until it was worked on by an over enthusiastic guitar tech and was never the same again. After that it didn’t play very well and the intonation was hopelessly wrong.

A possible reason was identified immediately

Wrap Around Tailpiece

The wraparound tail-piece was never a great idea in the first instance and this one was also tipping forward quite acutely. This type of bridge/tailpiece relies on a raised pattern to fix its intonation. Quite a crude idea which only allows for fine adjustment via two small grub screws hidden in the back end of the wraparound. This allows adjustment forwards or backwards ( or  ) and typically never gives enough movement to permit accurate intonation. 

 

Tailpiece Pull up

This has been modified at some point as it still shows the remnants  of the old tremolo system. And removing the scratchplate reveals some crude routing out for the humbuckers. Certainly not factory spec!

Open Cavity

It’s hard to say definitively but it appears that this guitar had a fixed bridge and fixed tremolo as well as single coil pickups. And at some point a previous owner has carried out all these mods.



 

Time to put it right

First thing is to remove the wraparound assembly and trem remnants.

Tailpiece removed

A modern wraparound is bought in to be fitted. This system has separate saddles similar to the Tune O Matic bridges. This will allow the intonation to be set accurately.

New Tailpiece/Adjustable Bridge Assembly

The threaded inserts that are buried into the guitar body are slightly smaller than the originals. Therefore the holes are plugged and re-drilled. To achieve this two Mahogany plugs a turn down on the lathe, inserted and drilled out.

With the scratchplate removed a few of the scratchplate screw holes are repaired.

Scratchplate Off Plugs Drilled

With the new wraparound bridge installed and the scratchplate secured correctly the guitar is ready to be set-up.

There is some fret wear which is honed out and the frets re-profiled. The fingerboard is cleaned and oiled and the guitar is re-strung with 10-46 gauge strings.

Bass Guitar Setups London: Sadowsky Bass



I had a visit from Jean-Louis Locas.

Jean-Louis is the bass player with Cirque Du Soleil who are performing their show “Kooza” at the Royal Albert Hall.

Jean-Louis has in his arsenal of instruments a beautiful 5 string bass by Sadowsky. The bass was in need of a quick set-up and a little fret attention mid shows.

Fender Guitar Repairs London: Stevens by Fender



Here’s an unusual guitar on the workbench.

A Stevens by Fender made by Michael Stevens.

Michael Stevens is a renown Luthier working out of Alpine, Texas. In 1986 he became the Founder and Senior Design Engineer of the Fender Custom Shop along with design engineer John Page. Together they designed and made guitars for many named artists. Read more here


This beauty has taken a tumble and the inevitable has happened, a broken headstock.

As evident from the serial number this guitar was one of the first few in the run. I can’t be exact as to where this guitar was made but the decal suggests it was out of the Fender Custom Shop.

The electrics cavity-cover bears two signatures and a date which adds to the intrigue.

It is decided that an invisible headstock repair should be made. This complicates matters as spraying a headstock with a coloured lacquer, so as to disguise the repair, will obliterate the decal. And the decal is essential to authenticate the instrument.

It will be impossible to save the existing decal as the finish on the back of the headstock will need to be scraped back to the Mahogany. After considered thought it is decided that new decals should be designed and made up.


Firstly the damage to the headstock is repaired, hot hide-glue is used for this. The break is clean with a large gluing area.

The neck and headstock are stripped down using a simple cabinet scraper. This ensures that the finish is removed in a controlled and careful manner.

The guitar body, fingerboard, edge-binding and headstock face are masked off and the guitar prepped for the spray booth.

The first coat is applied – this is the base colour mixed with clear gloss Nitrocellulose Lacquer

Layer upon layer of this mix is sprayed onto the neck to eventually fill the grain and to bring the finish up above the surface.

The water-slide decals are soaked, applied to the surface and left to dry.

The neck has several coats of clear lacquer applied. This gives depth to the finish and also offers protection for the decals

 

The surface of the neck and headstock are burnished and polished and the tuners reinstated.

All in all a good result and another quality guitar back in action.

Vintage Guitar Repairs London: 1930s Gibson L0 coustic Guitar Restoration





 

This lovely old Gibson L0 was made in the 1930s.

Exif_JPEG_PICTUREExif_JPEG_PICTURE

It was taken in by this workshop some years ago for an extensive rebuild. It’s had a hard life and had undergone some very strange repairs over the years.

The majority of the internal struts within the soundboard were loose and in a previous and mistaken repair attempt to stabilise the struts, Epoxy Resin had been smeared on the entire underside of the soundboard. Also wooden clothes pegs were glued here and there as a misguided attempt to strengthen various parts of the soundboard.

The bridge was missing. There were several splits and cracks on the soundboard as well as a distorted area around the footprint of the bridge. All in all the whole instrument was in a sorry state and on the verge of being discarded.

Fortune & Misfortune

Fortunately its neck, fingerboard and frets were in good order and the guitar was owned by someone who could see the potential in this old guitar.

After months of intensive restoration the guitar was finally restored and shipped off to its owner in the Midlands.

Much to his distress on arriving it was revealed that the guitar had been mishandled by the carrier during transit. Unfortunately the guitar had suffered catastrophic damage to its ribs.

Side Split 7 Side Split 6

Fortunately insurance had been taken out prior to the guitar being shipped and after much haggling with the carrier the guitar was returned to the workshop and work commenced on its second restoration.

The split was extensive and extended from the waist on one side to the waist on the other.



The Repair

The split had occurred when the guitar (in its case and packaging) was drop upright on its end. This caused a split that ran along the grain of the rib.

The broken halves of the split will need realigning and gluing back together. Also the area along the length of the split will need to be reinforced.


The splits are carefully aligned and glued

Made from old machine head parts and guitar strings, clamps are made up to hold the internal reinforcing strips in place while the glue dries

Small holes are drilled through the guitar rib for the string to pass through. Once tightened and the reinforcing strips are held in place.

With the glue dried the sides were lightly sanded, re-finished with a Shellac based lacquer and matted down.


I’m happy to report that the repair went very well and the guitar is now back in action again. No more National carriers though, this one is hand delivery only.

Acoustic guitar repair London: Gibson 1966 LG-0 (Hot Rod)





Here is an interesting project recently taken in by the workshop: a Gibson LG-O made in 1966

Image  Image

This is an all Mahogany guitar: Mahogany soundboard, back, ribs and neck. This guitar was a budget instrument at the time of manufacture and sold at an affordable price as an entry-level model. The guitar has a slim neck which measures 1 9/16’’ at the nut and joins the body at the 14th fret.

Exif_JPEG_PICTURE

The Bridge

In 1962 with many thousands of the LG-O sold Gibson decided to exchange the standard rectangular Rosewood bridge for a plastic “belly above” type. This plastic moulded version was held in place by 4 screws that attached from under the soundboard up into the base of the bridge. This was done for ease of removal when dealing with replacements. This was upgraded in 1968 with a Rosewood replacement which included an adjustable saddle.

Image  Image

 The Soundboard

The soundboard is ladder-braced with 5 lateral braces across its width. This type of bracing gives a distinctive tone that is indicative of the old acoustic Blues sounds of the 1930s. However, this system lacks structural strength and over time the soundboard can become bulged and distorted with string tension. The over large bridge-plate can exasperate the problem as these where generally made of softwood which also offered little structural strength. The LG-O was discontinued in 1974.



The Brief

Our Brief in this instance was to remove the internal ladder bracing, replace with a scalloped X brace system to give the guitar a more balanced tone and to accentuate the bass tone.

To upgrade the bridge-plate and to make and fit a Rosewood replacement bridge.



Removing the Back

In order to gain easy access to the internal bracing it will be necessary to remove the back.

This LG-O does not have an edge binding around its back outline. Therefore, a thin pallet knife is slipped between the back and the end block to start the separation. Once started a Japanese saw is used to precisely cut through the inner lining. Because of the saw’s thin blade and unique cutting motion very little material is lost during this process.

 

Image Exif_JPEG_PICTURE Image

Once the back is removed the simplistic ladder-brace system is revealed. You will notice that a brace and the bridge-plate are missing. I believe these became loose and subsequently lost years before. Their footprints are still visible.

Rosewood Bridge-Plate

The remaining braces are easily removed and the internal face of the soundboard is prepped in readiness for its upgrade. An Indian Rosewood bridge-plate is made up and fitted. Rosewood is the workshop’s prefered material for bridge-plate replacement because of its strength to thickness ratio.

Go-bars are a very handy and simple way to fit bridge-plates and braces. They are made from flexible timbers that allows pressure to be applied where needed whilst glue is drying.

The Bracing System

The bracing system is made up and glued into place piece by piece.

Each brace is made from 1/4 sawn straight-grained spruce individually scalloped.

 Gluing the Back

Once the bracing system is completed the back is cleaned up and glued into place

The Set-Up

The frets are showing some wear. They are honed and re-profiled and the truss-rod is adjusted.

The guitar is strung up and tested.

 Conclusion

I’m happy to report that the finished upgrade turned out very well. The guitar has a sweet sound with a good balance. It has a warmth and depth to the bass with sweet mids and trebles. It likes to be picked as well as strummed and I suspect that it will record very nicely and with a small body guitar that’s all you can really ask for.
