I have a 1978 Peavey T-40 (patents applied for) that burned in a gas explosion back in '91. It still plays well but has considerable burn damage. I was thinking of restoring it. It is worthwhile? I've seen these guitars sold for up to 500 bucks, but the body has to be sanded and re-varnished. I'm sure I can't recapture its original luster and I don't know if I do this myself. Has anyone done this before? Is it worth my time? A switch needs replacing but I don't know anything about electronics. I've already replaced the pickguard.
