Seen these before Fro, i like to call that one the "75 burst." Guild finished guitars in batches and with all the variations out there, many identicle pieces from the same year were likely painted side by side. a beautiful shade indeed, Gibson actually copied this color/burst, and a couple other variations of it, on the 2013/2014 USA series SG-J (satin/nitro). very attracive subtle fades on both the old Guilds and new Gibsons (especially with no pickguard). The OP has a beautiful JS-2 shortscale to go along with the X-702 long scale...tell us, which do u like better? mighty different beasts indeed!
