I’d love to know if there’s sure fire way of determining and how to see it. It’s a Custom Shop G&L ASAT, and I would think it would be a one piece body. It’s a killer guitar btw, tone. I’m guessing one look at the bottom would be good enough but I took pictures all around. The grains coming up and around make me think it’s one piece. When I see the grains around the neck pocket I think maybe not. It’s definitely a select piece of wood, It wouldn’t bother me at all if is a two piece body, would just love to know how to determine. Thanks guys. There’s another one piece to see, just scroll down a bit. #16 in the thread.
