    Anyone know when the preamp was fixed to stop battery drain, etc?

    Thanks!!!

    It wasn't only the preamp draining the battery but the bass in passive mode running through a flat preamp meaning no true bypass!. Bartolini has a wiring fix for this that can be found on Harmony Central. I never was aware that Fender indeed did correct this entire problem. I have noticed no one complains anymore about this problem which was originally noticed around the year 2000. I have done the modification to my bass with excellent results! As a matter of fact my battery has just been changed recently with the old one being there for four or five years! I play this bass very seldom and gig with it maybe once a year.

    This thread interests me. I have a MM5 that mows through batteries. Basically I have to change them about once every month or so, which seems excessive. I love this bass but this issue is definitely annoying. I'll be subscribing.

    Are you leaving the bass plugged in? Are you flipping the toggle switch to passive when your done? If you are doing both these things and you are still draining batteries than you need the wiring modification.
