I just picked up a Gibson SG. Its one of the GOTW series (week 37 67 SG Special) & has P-90s in it. With a distorted amp it sounds great for single notes but gets muddy for chords. Sounds great through a clean amp but again, alot less articulate on chords as well. Haven't much experience with these pups, so I'm wondering if this is normal for them or do they need adjusting? I'm considering taking it back if I can;t find better tones from it.
