    Okay straight to the point. i have a jazz bass, with two vintage, alnico single split coil pickups. what i want is the ability to 1: have a passive mode, standard jazz set up, a volume, volume and master tone. and 2: active mode, with an eq, bass and treble boost/cut.

    I fell inlove with the electronic system of the Carvin SB5000, after watching Ed friedlands reveiw on it. is there a pickup company offering an aftermarket kit like this? im not looking to buy a carvin bass, i wouldlove to have a modified jazz bass!

    here is the review!!! :bassist:

  3. I'd think a lot of preamps would be an upgrade from Carvin.
    Not that Carvin is bad, but they certainly aren't the best.

    I installed the 4-knob Deluxe version in my Peavey Grind 5, and am very satisfied. The Passive mode preserves the tone of the original Grind pickups, and the preamp has a really fat, warm and modern voice, almost synth-like. I especially like it with low mids boosted.

    What kind of jazz bass do you have? I would throw out looking into a Fender Jaguar as well as it already has that included and if you feel like changing the preamp it's just a matter of switching rather then customizing your bass.

    mike pope's preamp has the passive /active capability.
  8. Almost all preamps wired in a VVT configuration will allow for active/passive switching, since the volumes are before the preamp input, so the signal impedance does not change when the preamp is bypassed.

    I actually wrote that before you posted the Carvin, but it got posted after yours. Made it look like I was replying to your Carvin link, but I was really just replying to the OP's mention of Carvin :)
