So I’ve got a new SG 61 with the Maestro. Beautiful guitar! So a few notes on the fretboard have a sort of vibration, almost distorted sound when playing unplugged. Microphonic comes to mind. Doesn’t come through my amp. The sound is definitely coming from behind the bridge. I’m just curious if anyone has heard of this before and what the issue is as it’s my first experience with one. Thanks!
