    Advice please:help:

    I have a Bart equipped Jazz style bass with their 3 band 9v pre. I love the sound, but it has much less output than my other basses, even the passive ones. I have to turn up the amp so loud to get the normal volume that I introduce an unacceptable level of noise from my amp. The battery is good, I've checked the 2 trim pots on the circuit board, one seems to affect the the 'slap sound' you pull up on the Vol. pot for. I could not determine what the other was for, no real noticeble affect.
    Is this par for the course with the Bart's?

    That's not been the case for me. Barts, IME, have comparable output to other p'ups and preamps.

    I couldn't give top notch advice, but what I can say is ever bass I have ever had with barts were always lower output than compared to my other active bass. In fact now that you mention it even my passive basses when I have the -15db engaged on my amp. I never really had to crank my amp though, maybe just a half volume notch on my head or 1 volume notch on my combo. hope this helps.

    Interesting...if you have a Bart preamp you shouldn't see a circuit board. Barts are normally just a black box with a gain control, which has enough gain on tap to get stupidly loud. Got a pic of the preamp?

    I concur. The basses I own/have owned with Bart preamps had gobs of gain.

    Nor do Bart pre-amps have a "slap" switch by pulling the volume knob. Thats a Seymour Duncan pre-amp bro.

    Bart pickups typically have a wide freq response because of the lower output, there's no free lunch. Still with a typical NTMB preamp there's tons of gain.

    You are so very correct! I am barking up the wrong pre tree:rollno:

    Open up that preamp cavity. Bart pres have a gain control. Get a screwdriver and turn it up until you get the output you desire.

    Like Doug said, it sounds like a Seymour Duncan pre which does not have a gain control.
  12. and is VERY low output IME
