I have a problem at my bands rehersal room. I can't make the bass sound good and cut through at the same time! I've got a Fender Geddy Lee Jazz, Hartke 3500 head, Hartke VX410 cab and a Ashdown ABM-115 cab with Eminence Kappa 15 element. With the bass I always have to play with the bridge pickup soloed, because with both pickups on the sound is so bassy and muddy that I can't hear anything that I play. With the bridge pickup on it also sounds kind of muddy in the low register and it doesn't cut through, but in the high registers it cuts through to well and the sounds get harsh. I have to keep the master volume button at 7-8 to be heard. I've tried boosting the mids but that just makes the sound more harsh. I play with my fingers, and I would like to have that kind of classic rock sound (Blue Öyster Cult, Led Zeppelin...). The band consist of two guitars, a singer and a pretty loud drummer. I've also heard that the GL jazz and the Hartke head are known to be loud and cut through well, but not in my case. So does anyone have any idea what could be wrong?
