My Sigma solid body electric guitar looks like the American Stratocaster except for the headstock. It doesn't have the rounded shape on the end. It's brown with the wood grain showing through (stained) and fades out to black edges. White pickguard, 3 single coil pickups, slide selector switch and 1 volume, 2 tone knobs. Adjustable string bridge with a wha wha bar. 6 on one side tuners. A black stripe down the back of the neck. Made in Korea with serial #S99060222. The headstock says "Sigma Established 1970. I have a digital camera and could email you a picture. I don't know how to post a URL for public viewing. Near mint condition, I would say.

And not to change the subject, but another rare guitar I have is an S800 Epiphone with these words wrote across the front of the headstock in black letters. "Epiphone by Gibson" from 1986. Very nice condition too! Can't find much information on it either. I bought a price guide on ebay but neither of these two guitars are in it.
