    If I were to put in an Active/Passive toggle for a bass, would I buy the active pickups? Also, where can I find a diagram for the installation of one?

    Thanks

    Active pickups can't be run passive to the best of my knowledge. My Warwick uses passive pickups and an active preamp, pull up on the volume knob and the preamp is bypassed allowing for passive operation. I may be corrected here but this is how it works AFAIK.

    I donno how my G&L is wired, but I have a Passive/Active/12dB+ Treble Boost 3-way Toggle.

    I believe he is 100% correct. What kind of bass I you planning on working on?

    my custom bass. Its gonna be an EMG PJ setup with a B64 EQ and an 18V power supply (instead of the standard 9V). But Ive had My G&L batteries die on my and its so nice to just flip A switch, turn up, and keep playing, So I thought "I'm making a custom bass, so It's going to be made to make my life easy!"

    If you are using EMG pickups and your battery dies than you are SOL. You can't have a "fail safe" switch on a bass with active pickups. That works on a bass with passive pickups and an active preamp (like your G&L), but not the bass you are looking to build.

    Have you already bought those pickups? Or are you still just in the planning phase?

    purely planning right now. So if I bought say Villex pickups (www.villex.com), and then an active preamp, I could use the switch?

    Correct, you would have a passive pickup set with an active preamp. If you wanted to get -really- fancy you could have a passive tone control added (Like on a precision or jazz bass) so that you still have some tone control options while the bass is in passive mode.

    I'd get one with a bypass built into the design rather than an always on preamp and try to work out a good way to bypass it.

    So a SJB-3 quarter-pound for jazz bass and a Dimarzio DP127 with an Aguilar OBP-3TK active preamp would work?
