    Hey gang, does anyone have a diagram for the battery circuit fix for a Fender Marcus Miller jazz bass ? My bass is eating batteries like Gray Davis is spending our California dollars.

    I had that problem also,the bass ate batteries even when it was not plugged up! The problem is if you leave the switch on it drains the battery even if no cord is plugged in . For a fix of this problem go to Harmony Central.com, user reveiws,Bass/ browse by manufacturer,Fender/ Marcus Miller review and scoll down. I have done the mod myself and not only does my battery last but this modification bypasses the pre-amp in passive mode(doesn't run through pre-amp at a flat setting) and you WILL hear the difference. It will sound like a passive bass in passive mode. Hope this helps.
