my fender tone knob on my jazz bass seems screwy. when i turn the tone knob up the first few centimeters do nothing, then there is a HUGE jump in tone, then it is very sensative in the next centimeter then for the rest of the last half of the turn the tone moves up slowly and nicely. to get the tone i want i have like .00000001 centimeters of wiggle room. if i'm off by that much the tone is way off. :scowl: my concern is for lives shows i won't be able to make easy adjustments. what's up with that? also, do most people on here play with their tone knob on their bass all the way up or all the way down and make adjusments on the amp or do you play around with both?
