    I just ordered and installed a Bartolini 5.4 preamp in my bass. This is like the 7th one I've installed. However, this one has an issue. When I try to boost the bass knob, volume cuts out from the bass. I get no sound at all. All other knobs work like they are supposed to. I can even cut bass. But when I try to add bass, if I turn knob past 2:00 the volume cuts out. I even tried another new pot and had the same results. What the heck could be the problem? I've tried everything. Thanks in advance.

    Did you get this figured out?

    I have the same issue with my Treble and Bass, My Treble has to be up a little and bass cannot move out of the mid section, I wiggled the wires a bit and the fixed it once but now again I got that issue again. I bought this back in May of 2012.

    OK So this was my fix, I had to wiggle a post on the Treble knob, this fixed the issue with both bass and treble pots. Try this and see if that helps

    I had this issue on my bass, the problem was a bit of copper shield had raised and was touching one of the terminal on the bass control...

    If you have copper shielding in the control cavity, a good thing to do is put a strip of electrical tape under the terminals on the pots. That helps to prevent shorts.
