So, here's a few pics of a garage sale find. I picked this up in a garage sale for $200. I don't care about the value, as I know, it's been pretty beat up... I am just trying to figure out what it is... since the switches have some static in them and need to be replaced. it has a couple peculiar touches to it. Tracing the serial gives me: Your guitar was made at the Kalamazoo or Nashville Plant , USA approximately in: 1970, 1971 or 1972. The serial reads 640125, stamped into the headstock. Clearly the original finish is gone. The stickers add a nice rock touch... well, it gives this piece character at least. LOL. She plays like a dream. The bridge plate is the curious piece to me. I can't seem to find anything like it. The knobs and switches appear to be those from an SG 200; but the pickups would say different. And the original pick guard is non-existent. I'd like to replace at least that much. The tuners have been replaced with grovers.
