Pre amp question

[Drop1]

More specifically East uni.
Does anyone know if pulling the passive switch cuts power from the pre?

I'm eating batteries.

I assumed putting the bass in passive mode cut the power to the pre but I'm only getting 3 days per battery.

Do I need to unplug the bass or switching to active enough?

With most preamps, plugging the cable in turns the battery on. Typically, a passive switch bypasses the preamp but leaves it on. I don’t have an East pre but I can’t imagine they do things much different.

I'm a believer in always unplugging. It sounds like it's pretty easy to test. Preamp bypassed, bass unplugged, extended battery life = switch leaves battery in the circuit. Do that and batteries last 3 days (which is a ridiculously short period of time. A new battery should last weeks/months depending on usage) = you've got deeper issues.

Give it a shot, if you still have problems contact East.

Yep, you need to unplug.

Looks like I'll be adding an on/off switch.

Search the forum and read about it a little bit more before deciding.

If you are getting less than 6 months from a battery you may have a leak to ground somewhere.
