LR baggs circuit inside Godin Acustibass drains battery like crazy

[RHartvig]

Hi everyone. So i just recently bought a used Godin LR baggs Acoustibass and my god does it sound amazing. Sadly i found out it has an issue with draining the battery really really fast, even when not plugged in. It will drain the battery in about 7-12 days. It is the dual 9v model. Checked to see if the problem was located in the jack but everything seemed fine there. I even installed a killswitch to cut off the circuit but it still drains like crazy. Can anyone give any insight into where the problem may lie? I tried resoldering the connections etc. but no luck. Hope someone can help out as there

Hey RHartvig,
I replied to your email a little while ago. Let me know if you didn't get it.

Hey Caleb,

I have an Acoustibass with the same issue. It draws about 4.5 mA from the negative rail 9V battery (the one with - on -, and + on the +- combined with the positive rail 9V battery) without a instrument cable plugged in. About right, measuring the DCR across the battery terminals with no battery no load is 3.4kOhm. Hard to say exactly since yall (understandably) don't distribute your schematics, but it seems like some part somewhere might have died.

I've checked all the parts and nothing looks particularly broken. Other than some resoldered battery wires, the board looks untouched (since 1991)!

Ideally we could fix this just over message/email. Is this a known issue, maybe the above poster has the exact same broken part as I do?

Thanks for the help!

I had a couple of emails back and forth with the original poster on this thread, but I never heard back if the things I mentioned actually helped or not. If you've checked the jack for a short, which it seems you have, it would seem like the issue would be related to the power switching on the board. If you want to email me directly at [email protected] with a picture or two of your preamp, I will see if I can dig up some helpful info for you.
