Hi Lionel
As the risk of repeating things that i've written elsewhere on this forum, the guitar in the avatar is truly the Artist that I've been describing. The Bigsby was fitted to the guitar when I bought it in 1963 - the assumption is that when this very early Artist was made, Jim Burns had not actually produed his own design of tremolo (none of the Artist guitars had tremolo) so this must have been a 'special order' and Jim used the only commercially-available solid-body trem, whcih was the Bigsby. There are no other screw holes in the body, so it did not start life with the fixed Burns tailpiece.
The reason for the change in body colour is described in my earlier message and the electronic have been changed many times over the years.
However, the body is still the same unique Artist shape and the wood is a rich red-brown mahogany under the paint. (Paul Day has said that Jim used to salvage old saloon-bar mahogany counters). The neck has the offset contour that only the early guitars had and the machine heads and strap buttons are original (along with the pickups, of course). The frets are a bit worn in places but all 25 are original. Tucked away in a jiffy bag are the original pickup selector with parts of the wiring harness attached, along with the rhythm-solo switch, the original bridge and the special 1/8" jack socket and matching plug. In my 'pots graveyard' box I might even have some of the original pots (if only I knew what they looked like)
Maybe one day I will have the body sprayed cherry-red again and return the guitar to the original condition in which I bought it!
