    I've got a Carvin 6st fretless that uses active pickups to provide excellent tone, punch, and good low end response. The problem lies with the fact that the presence of the bass goes away after about two hours of steady (rather vivatious) playing. I'm wondering if others have found this to be the case. I was also wondering about rechargables.

    Any suggestions?

    The battery should last at least 6 months in an active bass. You should have the bass looked at by a luthier to see if there is a problem. Good luck

    My Cirrus batteries would die after one month of normal playing. Got to where I had a battery tester and a fresh set at all times in my bag. When they died, no sound!

    Do you unplug it when you're not using it? You need to do this or the battery will drain very quickly

    good call.

    It's an old trick of using a stereo jack like a switch to turn
    the battery on. When you plug your mono cable into the
    jack, the ground sleeve of the plug completes the ground-to-
    circuit from the battery.

    You can sorta' get an idea how it works from this diagram
    of a simple P type setup from the EMG site...

    A long time ago I had an active Dean bass that ate a battery every week or so. Turned out to be bad solder in the jack and the circuit was always on.

    I had a Carvin LB76 that had a problem similar to this, it turned out to be a bad input jack.
