Hi, everyone. This is my first post. I went through some threads on muddy sound but didn't find what I was looking for. So I have a PJ bass (Korean-made Spector), not a USA-made one but for now it has to do. Then for strings I use nickel-wound D'Addarios. My amp is a Trace-Elliot head with 2 cabinets of 2 10" speakers each (so 4x 10s in all) on top of an other 2 cabinets each with 2 15" speakers (that's 4x 15s in all). My amp's huge and I'm quite satisfied with it. I set my EQ completely flat and play on both pickups but wish to get a brighter sound. Strings are obviously new. I'm thinking it could be the P-pickup. I was thinking of changing it to an other J-pickup. Any opinions, please?
