I am sure i must have connected up my East preamp in a funny manner, as activating passive mode ( just a quick knob pull matron ) and it dwarfs the volume of bass when it was in active mode. If anything, i would have thought active would be louder than passive, or at least equal. But what do i know. I'm a dummy with leccies
Its not right though, whatever is going on. The difference is too great. If anyone has a clue about wiring and whatnot... give us a clue 👍
PS. its a 5 knob active / passive Uni-pre no toggle, and i'm utilising a 2nd battery , as my Ibanez PB770 is 18v to start with.
