So I recently just bought an ex display Gretsch G5422T. It sounds and plays really good and it’s a bit of an improvement to my last guitar. But I noticed something strange when messing around with it. If i held the guitar with the strings facing the ceiling the signal from the amp with just cut out and no sound will come out of it ? It’s done this randomly and I’ve been trying to troubleshoot what’s wrong. I’ve check cables and amp which seems fine. I’ve never had a hollow body before so I didn’t know if it had something to do with it being a hollow body ?
