I've been playing bass for about 5 years but I've always focused more on technique and song craftsmanship than tone. My snarly scratchings are beginning to bug me and I would appreciate some advice!
I currently use a Musicman SUB bass, I have the Bass and Treble knobs both at full. I play a battered old Stagg Amp where I have Bass 3/4, Low Mid Full, High Mid 3/4 and Treble Full. It's a bit scratchy and mean-sounding, which is great when I'm playing metal stuff, but I want a warmer, poppier tone.
Think Mark Hoppus.
Any help would be much appreciated!
(Also if I've said anything that shouldn't be said on bass forums forgive me, this is my first post

)
PS. I play with a pick.
