    i have a specter ns2000 Q4 bass and i took off the back pannel just to check it out last night. i noticed a second set of wires coming from the PUPS. im not sure but i think that all id have to do is add a battery box and they would be activated am i correct or horibly misguided?

    You're misguided.
    Simply adding batteries won't work.
    You need to install an EQ or line-buffer circuit that is active (active = needs a power source to work).
  3. So too, even in its simplest form you could build a small pre-amp with a tone control out of a simple Opamp you buy from Radio Shack... but thats all electronics.

    In another words, like JMX said, you cant add batteries, you need the signal from the pickups amplified slightly and the amplifier needs power to run... thus the battery.
