Thread title says it all, really. My bass and amp are generally pretty quiet in operation, but when I use my pedal board the hiss starts to creep up. I know this is unavoidable really, but any suggestion for keeping it to a minimum would be welcome. I've tried rolling off the highs a bit and playing around with relative gain settings, but the hiss is still more than I'd like, although playing live it's not a major problem. Signal chain is bass > digitech bsw > mxr bass auto q > sansamp pbddi > boss ceb3 > amp. All the effects are powered through the adaptor for my Boss pedalboard, but it's hiss that's the problem rather than hum, so using batteries makes little difference.
