Hi, I had almost decided to buy a Zvex Wooly Mammoth, and then I discovered the issues with active basses. Apparently it works fine on passive basses. My point of ignorance is that I have an Ibanez SRX500 which has passive humbucking pickups, but active EQ. Does that mean it falls on the side of workable (with maybe the volume rolled off) or will it act like an active bass with respect to the fuzz? By the way, if the problem is input gain into the mammoth, why don't people just use the bass' onboard volume or a volume pedal to correct the problem? Please help.
