    hey y'all, i want to install 2 emg active jazz pickups and an emg preamp with bass and treble eq controls.

    is it possible to run both pickups and the preamp with a single 9-volt battery?

    is it advisable?

    Yes, that's how it's done for the most part. You'll hardly see powered components on different power supplies in a bass guitar.

    thanks for the quick response. i'm contemplating a transplant from an 18-volt-equipped donor bass but the recipient bass patient has very little room for one battery, much less two...
  4. EMG's stuff is designed to run at 9V, with 18V being an option for more headroom.

    bumping this to ask another emg question:

    with a fully active emg system, is there any need or advantage to grounding the pots to the bridge?

    No, it's not recommended to ground them. The ground on the jack uses the amps ground to ground everything when plugged in. It's also the on / off switch for the electronics.

    Their own instructions state that you'll be fine at 9V, unless your pickups are "high output" and you play "aggressively", in which case you might experience clipping and should move to 18V. Not very helpful, is it? :)

    quite helpful, actually! i'm moving the restification in a differnet direction. i picked up an 80s set of emg pickups with controls and will use that in the 80s heritage bass i am working on. thanks y'all!
