Hey guys, I own a Peavey Foundation and I have been trying to figure out its age. The SN is 03820575. It also says on the back of the head stock 'U.S. patent NOS. 4,237,944; DES 255,462 and patent pending'. It has Super Ferrite pickups and the classic Peavey symbol on the head instead of the block lettering. Anyone have a clue what year it is from? Thanks.
