Bought this in 2000 for $650. No serial number. I've heard that some 70s SGs had sticker serial numbers so maybe? Pots were replaced in 1989 or later, based on serial numbers and soldering work. The volume and tone knobs are not original, because I replaced them. A previous owner removed a Bigsby or something like it and replaced it with a stop bar. Plays pretty well. Has a very thin neck.
