Hi guys. New member here. so i got my hands on a SG Custom Shop Pilot Run with a batwing pickguard. It has 57 Classics with Alnico 3 magnets. The SG sounds wery resonant and loud unplugged, but dull, muffled and low output through my amps compared to my Les Paul. I switched the pickups over for both guitars (throbaks in the lp) - same result. The LP sounds open, more bright with more bite. The SG still dull and muffled. Could this be a wiring/pot issue?
