Hello all. This may sound dumb, but I'm curious. I own a Hohner BBassV, It uses passive EMG Selects pickups with an active preamp. The preamp has an output pot on it. My question is:When playing in active mode, is more battery power consumed if the pot is turned all the way up, or is power consumption always going to be the same regardless of how the pot is adjusted? I play with both volume controls wide open. The pot is not fully wide open, but close to it. Was interested as the bass crapped out on me during a practice one day and I had changed the battery earlier this year. The previous battery lasted a lot longer than that. As long as nothing is plugged in, the preamp will not work. This bass is not as loud or full bodied as my Series 10 P-Bass Replica where I had the factory pickup replaced with a Fender "Original '62 p- bass pickup".
