Hey guys! I have bought an older SG and I'm almost certain it's a 67 but it does have a Bigsby. I didn't think that was an option? The pots date 66, the serial is barely visible but leads toward a 67. Frets are very wide and low, not worn down....without intentionally throwing the term around, maybe the "fretless wonders" The inside has the swimming pool routing. There are no marks from a previous Vibrato, so the Bigsby has always been there. It has not been re-finished. Everything is actually all original. The neck PAF is missing it's cover but it is the real PAF. Great site! Any help is appreciated! Glad to be in the vintage SG club!
