so, did i fairly loud jazz gig last nite, crammed onto a small stage an for the first time i was expereincing a lot of feedback on the dble.never had it b4 and dont really know how to go about resolving it. I basically was getting asked to turn up and up but coulnt because I was just getting wailing feedback. I managed to tame it by keeping my knee on the back of the bass, reducing the overall resonance of the thing but it still didnt help much on the volume side of things. Would an EQ pedal help? I have a boss 7band bass eq pedal. I've got to play this gig again next week and it would be go to have it sorted by then. I;ve got a k&K bass master pro set up (4 piezos on bridge and an underfoot) going into a Hartke 1x12 kickback. any suggestions greatly appreciated!
