    Long ago player getting back into bass but I have a question for the gurus out there.

    The basses I own are:

    Peavey Fury IV (newer model stock pickups and preamp)
    Warwick Rockbass Vampyre (MEC Pickups and preamp)
    Conklin GT4 (Bartolini pickups and preamp)

    The issue I am having is that the Peavey is about twice as loud into the amp and processor as the other 2. I have to back off the volume quite a ways to get it to be even with the other basses. I popped the back of all 3 basses to look at the preamp modules and it appears that none of them have any sort of level adjustment. Anyone know why this would be such a difference?

    These are the basses:



  2. See if there is an internal gain trim pot on the preamp that is set too high.

    That is actually the first thing I looked for and no luck there. It's a sealed unit.
  4. Adjust pickup height.

    Tried and no major difference. The Peavey is bottomed out as low as it will go and the other 2 are raised up where they should be and still the Peavey is a boomer. I am wondering if the preamp in the Peavey is just that hot.

    Some preamps are hotter than others. The ones in my NYC Sadowskys are really hot.

    That's kinda what I was thinking. I went through the Conklin last night and there was a loose wire but it didn't make a difference.

    You could just put a trimmer into the cavity and wire it like a volume pot. Then leave it at a suitable setting.
