    My question is very simple: is it possible to wire a MEC active preamp with independent volume controls? Thanks.

    How?
     
  4. Two volumes into the input. Same as any other dual-volume setup.

    Where would you put the additional volume pot(s), though?

    I ask because, according to this diagram, the signal from the pups goes first to the treble pot, and then the entire signal from both pickups goes into a volume/blend push-pull as a result of them both going to the treble pot first.

    That's for the single-pickup FNA bass.
    Which model do you have?

    Oooh, didn't notice that.

    I don't have a Warwick bass, I'm just wondering because I want to put a MEC preamp in a three-pickup custom build.
     
  8. I can't see it too clearly. Looks like a series/parallel switch. There is no connection from the pickup to the treble pot. The pot goes only to the preamp.

    The two volume pots will output to where that pickup inputs.

    I had to replace a push/pull volume pot in a 2 band MEC and was able to decipher the wiring well enough to get it done. They are complicated, but are just preamps.

    Most likely, if you have an MEC preamp, the signal going into it can come from any number of passive configurations. As long as they have a "Hot out", you can put it into the preamp.

    Thank you very much! That's exactly what I needed to know.
