Does anyone know what pots (Ohms) should be used with EMG PJ Active set up? I have two instruments and the output is significantly lower on one that has generic pots in it. My other bass has EMG pots in it and clearly sounds better with more output. I already bought and installed a BTC preamp, so I would hate to have to buy a whole pot kit. I'm wondering if the generic pots are the issue? Thanks for the help!
