OK, please don't kill me if it is answered before. I hear only good things about Ernie Ball Volume pedals. But I'm not sure which one should I get. If I play a passive bass but connect them to a lot of effect pedals (booster and distortion etc.), should I get the one for passive instruments or the one for active instruments? And I have passive basses as well as active basses. If I buy the one for active instrument, may I be able to use with passive basses. And vice versa?
