I just recently picked up a '06 American Fender P-Bass from a used guitar store. Brought it home, strung it with La Bella flats, and intonated it. I started playing it through my Ampeg B200r and realized the tone I was getting was a little harsh. My EQ is relatively flat w/ a small bass boost, slight lo-mid boost. For example if I play eighth notes on the low G on the low E string it sounds a little middy and hollow. I want to aim for more of a rounder sound with the flats/P-bass combo but I feel like i'm not getting that with my set up. Any advice as to what I can do?
