I think the serial # on the guitar was in fact 1968... Gibson serial numbers at that time are notoriously random. It was a cool little guitar in it's own right, even before we modded it with a set of Stewart-MacDonald Golden Age humbuckers and pre-wired harness. At least it let me keep all this stuff intact.
Forest and Joey will get a kick outta' this... though they had nice maple necks with rosewood fretboards, an adjustable truss rod, even all the same hardware as their Gibson counterparts, the bodies of the Kalamazoo instruments were made of this mysterious greyish-beige composite. I later read that Gibson had contracted another local business to mold them. Their main gig was molding (wait-for-it) toilet seats. Yeah... no joke.
I actually had a guitar and a bass. =)
