Lately I've been playing Jazz Ensemble at school. Its a very nice experience, but im having a major problem that no one seems to sympathize with. My low end isn't low enough. It's really a new experience for me. My tone is almost always overpowering the band even when my guitarist is playing, and the amp is turned down waaaaay low. SO how do i get a more bass sound? Ive tried every conventional method (i.e. turning the Bass knob up and the Treble knob down.) Any suggestion?
