Passive twice as loud as active ?

[fleabag]

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.

Check the trim pots for the pickups aren't all the way down

Cheers lemmy - will have a look in the morning.  No rehearsals till next friday, so i have time.

Rather handily the trim pots for the pickups (and also the three jog wheels for the bass/treble frequencies) are accessible when the pre is installed so should be realtively pain free. Should just need a screwdriver to adjust them.

 

I've just put an East Uni in my backup bass, it's pretty transformative but unfortunately I want one in every bass now.
