Restoring Vintage Guitars - Part one

My name's Mike from Cambridgeshire and I've been restoring guitars for over 30 years; now retired but keep my hand in with my own stock. Please don't ask me to restore your guitars now that I am retired.

Firstly you have to decide if it's a valuable vintage guitar or just a cheap copy that is worth perhaps £50-£100.
If it's a cheap one you can basically do what you like with it as you are unlikely to reduce or increase it's value much.

If it's a valuable guitar, perhaps several hundred to several thousand pounds you need to be very careful what you do with it.

Beware: if you refinish the body and neck you are probably going to immediately slash it's value by half or more.

Collectors of vintage guitars (like collectors of antiques) like their guitars in as near original condition with all the parts original as it would left the factory. A certain amount of wear and corrosion to the metal hardware is acceptable and indeed in many cases proves it's age. If it's a vintage one and looks brand new it may be mistaken for a re-issue which many manufacturers produced from the 80's to the present day. Buyers would be very suspicious of say a 1965 Telecaster in mint condition; I doubt there are many out there other than perhaps Fender's own collection.

If you are going to attempt to restore a vintage guitar you need to do it 'sympathetically', keeping as much as possible original. NOS (new old stock) parts will stand out like a sore thumb and decrease it's value. If you have to replace pick-ups because they are faulty then try and obtain an original vintage part from a scrap guitar. Volume and tone pots are another grey area; if you need to replace them save the originals as these (via date codes on them) can help to date a guitar. Always keep any removed parts and give them to the buyer if you ever sell the guitar; it would normally increase it's value.

Restoring Vintage Guitars - Part two

Where to start...
I always remove the strings first; you will need a new set when it's finished anyway.
If the hardware, scratch plate and machine heads are easy to remove take them off for cleaning.You may have to remove the output jack socket if it's mounted into the wood body.

Removing the neck if a bolt-on type may not be necessary to clean the body and neck but may reveal the date of the guitar as often codes or dates are pencilled on these parts.
Get a bottle of T-cut (available from any motorist centre) and clean the body and back of the neck with this cream using a piece of cloth. This will remove any surplus dirt and restore the finish to some degree. When you have polished off all the excess cream give the body and back of the neck a good finish of proper guitar polish. Use it sparingly as it can be difficult to polish off. Use a clean duster for this.

The fretboard...
I have a thin brass sheet with a slot cut out, the width of the widest fret, which I place over the fret and polish along the length of the fret with a piece of 000 or 0000 gauge wire wool. This will polish them without removing any actual metal. Continue to polish all the other frets in a similar fashion. Around 4 to 6 strokes with the wire wool will normally polish them bright.
Next I use a similar wire wool grade to polish the spaces between the frets with a coloured natural polish ( I use one called Black Bison which is used in the antiques trade) but any good stain polish should do.
Be careful if you have a light natural finished neck and use clear polish for that.

I clean all the chrome parts with Duraglit, now called Silvo. Machine heads should be cleaned and then lubricated with a tiny drop of oil on the gears and ends of the tuner rods. The pots should be given a squirt inside of switch cleaner (Servisol or any comparable make) but not WD40 as this leaves an undesirable residue. A tip is to try out the guitar before you strip it and check if there is any crackling as you rotate the pots.
If they are very 'noisy' they may need replacing but may be able to be restored with the switch cleaner; no real way of telling until you have reassembled the guitar.
You are now ready to reassemble the guitar. Keep all the original screws if possible but polish the heads with a brass wire brush first to clean them up.

Finally fit a new set of strings and tune up. Some collectors like to save the old strings so you can put them in the packet and mark the name of the guitar they came from.

Hope that helps and gives you hours of pleasure like it does me. :)

Good post mike
 
Here are two things i'd add straight off.
 
1) always take photos BEFORE you start. It's very easy to forget which way round something goes, which side the washer was etc.... Or a wire suddenly comes lose... where was that soldered to again? Doh!
 
2) keep any removed parts together in a safe place. It's easy to mislay a screw or two otherwise. Especially important if you are not going to put it back together again immediately. Bag it up and label it.

Indeed Jules; small screws tend to depart into another dimension or universe if you leave them on the bench and go to bed. :shock:

1970 Rosetti Epiphone guitar catalogScan of 1970 Epiphone guitar catalogue produced by Rosetti for the UK market. Undated but most likely from mid-late 1970, this was the first UK catalogue to show the new range of Japanese (Matsumoku) Epiphone guitars. Interestingly, these pages show the Epiphone solid bodies with a single-sided Fender-style headstock layout - a feature quickly replaced with a typical two-sided Epiphone headstock almost immediately. Epiphone electric guitars: 9520, 9525; bass guitars: 9521, 9526; acoustic guitars: 6730, 6830, 6834
1971 A World of Guitars by Rosetti catalogueScan of 1971 Rosetti catalogue (UK) featuring guitars from from numerous manufacturers worldwide: guitars by Epiphone, Hagstrom, Levin, Hoyer, Egmond, Eros, Moridaira, Kiso-Suzuki, Schaller, and Tatra.
1971 Selmer guitar catalogueScan of 1971 Selmer guitar catalogue showing the range of electric and acoustic guitars distributed by the company: guitars by Gibson, Yamaha, Selmer, Hofner and Suzuki. 1960s Selmer had always placed Hofner at the front end of their catalogues, no doubt these were the better sellers - but into the 1970s Hofner were slipping somewhat and only appear at the tail end of this publication, pride of place going to Gibson, and to a lesser extent Yamaha. In fact this is the last Selmer catalogue to include the many Hofner hollow bodies (Committee, President, Senator etc) that had defined the companies output for so many years - to be replaced in the 1972 catalogue by generic solid body 'copies' of Gibson and Fender models. A number of new Gibson models are included for the first time: the SG-100 and SG-200 six string guitars and the SB-300 and SB-400 basses.
1968 Selmer guitar catalogueScan of 1968/1969 Selmer guitar catalogue (printed July 1968), showing the entire range of electric and acoustic guitars distributed by the company: guitars by Hofner, Gibson, Selmer and Giannini. Selmer were the exclusive United Kingdom distributors of Hofner and Gibson at the time, and this catalogue contains a total of 18 electric guitars, 7 bass guitars, 37 acoustics, and 2 Hawaiian guitars - all produced outside the UK and imported by Selmer, with UK prices included in guineas. This catalogue saw the (re-)introduction of the late sixties Gibson Les Paul Custom and Les Paul Standard (see page 69) and the short-lived Hofner Club 70. Other electric models include: HOFNER ELECTRICS: Committee, Verithin 66, Ambassador, President, Senator, Galaxie, HOFNER BASSES: Violin bass, Verithin bass, Senator bass, Professional bass GIBSON ELECTRICS: Barney Kessel, ES-330TD, ES-335TD, ES-345TD, ES-175D, ES-125CD, SG Standard, SG Junior, SG Special GIBSON BASSES: EB-0, EB-2, EB-3 - plus a LOT of acoustics branded Gibson, Hofner, Selmer and Giannini
1961 Hofner Colorama IHofner Colorama was the name UK distributor Selmer gave to a series of solid and semi-solid guitars built by Hofner for distribution in the UK. The construction and specifications of the guitars varied over the period of production, but by 1961 it was a totally solid, double cutaway instrument, with a set neck, translucent cherry finish, six-in-a-row headstock, and Hofner Diamond logo pickups. Available as a single or dual pickup guitar, this sngle pickup version would have been sold in mainland Europe as the Hofner 161.
1971 Commodore N25 (Matsumoku)Commodore was a brand applied to a series of guitars produced in Japan at the well-respected Matsumoku plant from the late 1960s to the mid 1970s - and sold primarily (perhaps exclusively?) in the United Kingdom. The models bearing the Commodore name were all guitars available from different distributors with different branding. Although there may have been some minor changes in appointments (specifically headstock branding) most had the same basic bodies, hardware and construction. Equivalent models to the Commodore N25 (and this is by no means an exhaustive list) include the Aria 5102T, Conrad 5102T(?), Electra 2221, Lyle 5102T, Ventura V-1001, Univox Coily - and most famously the Epiphone 5102T / Epiphone EA-250.
1960 Hofner Colorama IIThe Hofner Colorama was the name given by Selmer to a series of solid (and semi-solid) body Hofner guitars distributed in the United Kingdom between 1958 and 1965. The Colorama name actually applied to some quite different guitars over the period, but in 1960 it was a very light, semi-solid, set necked guitar with one (Colorama I) or two (Colorama II, as seen here) Toaster pickups. Although an entry-level guitar, it was very well-built, and a fine playing guitar; certainly a step up (at least in terms of craftsmanship) from many of the Colorama guitars that would follow, and a good deal of the guitars available in Britain circa 1960.
1971 Epiphone 1820 (ET-280) bassBy the end of the 1960s, a decision had been made to move Epiphone guitar production from the USA (at the Kalamazoo plant where Gibson guitars were made), to Matsumoto in Japan, creating a line of guitars and basses significantly less expensive than the USA-built models (actually less than half the price). The Matsumoku factory had been producing guitars for export for some time, but the 1820 bass (alongside a number of guitar models and the 5120 electric acoustic bass) were the first Epiphone models to be made there. These new Epiphones were based on existing Matsumoku guitars, sharing body shapes, and hardware, but the Epiphone line was somewhat upgraded, with inlaid logos and a 2x2 peghead configuration. Over the course of the 70s, the Japanese output improved dramatically, and in many ways these early 70s models are a low point for the brand. Having said this, there are a lot worse guitars out there, and as well as being historically important, the 1820 bass can certainly provide the goods when required.
1981 Gibson MarauderProduction of Bill Lawrence's Gibson Marauder began in 1974, with production peaking in 1978. But by 1980 the model was officially discontinued, though very small numbers slipped out as late as spring 1981. Over 7000 examples shipped between 1974 and 1979, and although no totals are available for 1980 and 1981, it is unlikely production reached three figures in either of these years. These final Marauders were all assembled at the Gibson Nashville plant, and had some nice features not available through the later years of production, such as a rosewood fretboard, and in this case, an opaque 'Devil Red' finish. It's a great looking and fine playing guitar!
