Shergolds have their own very distinctive characters. Consider:

They are not pretty.
They are not "comfort contoured".
They are not "ergonomically balanced".
They are not light weight.
But they are not copies of anything else!

Shergolds are probably the only quality guitars on the second hand market that are truly original, uncopied, "vintage", and affordable.
For the price of a mediocre modern Str*t lookalike, you can have an inovative and distinctive piece of British guitar history that is guaranteed to be a talking point with other guitarists.
I have met very few guitarists who have anything but praise for the necks on Shergolds and most like the distinctive and versatile sounds of the unusual switching systems.

The most important test of if the price is reasonable, is if you feel you've got value for your money. For those of you outside the UK, I would expect the prices to be quite a bit higher (is this correct? Emailme with any price info you have) as export was not a huge part of the Shergold market (Norway and France seemed to be the fairly major importers, so Shergolds should be more common in those countries).
Any UK and non-UK prices and indicators of availability would be appreciated. Drop me a line by email if you have any information.

Notes

• The "Custom" tag in the names of some models is a bit of a misnomer.
  "Custom" models can usually be thought of as the "Mark 2" model. But I think you'll agree, "Custom Masquerader" sounds better than "Masquerader II" or similar variations. However, some sellers latch onto "Custom" and lift the price accordingly.
• At the moment there is a very small collectors market for Shergolds. Hence prices tend to be based mainly around a guitars practical points rather than how old it is or any of the other things that afflict original Burns guitar prices now.
• Guitar prices given are for six string versions. Add between £50 - £75 for twelve string versions on average or top condition examples. Little extra value if buying a heavily damaged one.
• Modulator modules sell for between £25 and £50 depending on condition and model. The rarest and hence most expenive are the Super Booster, Quad and Recording modules. The Recording module is the most commonly sought after.
• Six string basses are difficult to price (as are fretless models). It depends very much on the current fashion for six string basses more than the fact that they are Shergolds.
  When unfashionable, dealers have been known to discount them heavily, and then when back in fashion to add a huge premium. Exercise your judgement if six string basses are your thing and it appears expensive.
  Also, remember that Shergold 6 string basses were built on a 30 inch scale (only a few custom orders were built to 34 inch) and so are more a Bartione guitar (EADGBE tuning, 1 octave down from normal guitar pitch) than a normal multistring bass (generally CEADGB tuning).
• Double Neck prices are an average of the three combinations available. The two combinations with twelve strings tend to get better prices.

• Average Price is the price that a good playable example would fetch reasonably easily. These will generally not be exceptionally good condition, but not fatally damaged either.
• Low Price is the price for damaged or broken examples on the understanding that you would either be spending a fair bit on repairs or that is is possible that they will be dismantled to repair others.
  Examples that have suffered obvious DIY conversions fall into this category. Again, really bad damage (a warped neck or split joining in the body for example) probably makes the prices given irrelavent. Remember that original or even look-alike parts for Shergolds are pretty much unobtainable now.
• High Price is the price for pristine examples probably with a good owner history and with all parts (covers etc) and a less common finish (green burst, translucent colours etc). The guitar must be exceptional to justify this much or any more. An original fitted flight case should be expected in this price range.

Bear in mind that it is still possible to find real bargains. Look out especially for "bargain bin" offers on really battered and dirty Shergolds. My '76 Modulator was one of these and cost £125 with modules 1 and 5. £15 to have the binding on the neck repaired, a hour or two with a soldering iron replacing capacitors and wires on the modules, a good polish, a new set of strings, and it was ready to rock!
Doubles can also be found at good prices. My white '85 12/6 cost £300 from a private sale and required no more than a good clean, a new stereo jack socket, and a bit of time to set the intonation correctly.
Other Shergold owners have reported that car-boot sales, charity shops and garage sales have yielded cut-price Shergolds for (in one case) as little as £10!
