I have read that tenon lengths were not consistent in the 1960 models. Don't know if that is true. Do some searches. There have been discussions here and at that other forum on this topic
Wait, wait, wait! I thought we all agreed this was because the dot was over the "I" in the Gibson logo or not?!
Joe is talking about one of his Bursts from 1960. He talks like the Bursts from 1960 had a little smaller neck tenon in general.
