Bassist on the Run Posted November 13, 2023 Share Posted November 13, 2023 Anyone have an idea why my bass is eating battery’s like there going out of fashion. My jack cable is unplugged every time I finish playing and only use the bass lightly so not on a daily basis any help would be appreciated Quote Link to comment Share on other sites More sharing options...
Bigguy2017 Posted November 13, 2023 Share Posted November 13, 2023 It does have a 'stereo' output jack that switches the preamp on / off ? Quote Link to comment Share on other sites More sharing options...

How would I know this mate I’ve never heard of this. I just assumed a jack was a jack. It has a push pull pot that turns on or off Quote Link to comment Share on other sites More sharing options...
Bigguy2017 Posted November 13, 2023 Share Posted November 13, 2023 Does the push / pull switch disconnect the power to the preamp or just switch it in / out of circuit? Asking as the most likely reason for battery drain is continuous power to the preamp. Quote Link to comment Share on other sites More sharing options...

Asking as the most likely reason for battery drain is continuous power to the preamp. It seems to make a difference in sound when I pull up or push it down. I have to turn down the pre amp as it was ridiculously loud. But the battery died again today and I only replaced 3 weeks ago and haven’t used it since it was replaced Quote Link to comment Share on other sites More sharing options...

lemmywinks Posted November 13, 2023 Share Posted November 13, 2023 (edited) Your 3B will be the volume (push/pull), blend and stacked bass/treble if it still has standard Corvette controls won't it? https://cdn.shopify.com/s/files/1/1941/7837/files/2B-3b_epoxy.pdf?744051323792808354 Does your output jack have two or three lugs on it? With active basses the jack is used to complete the circuit across the sleeve and ring so when you unplug the cable it doesn't drain the battery, that's why they use a 3 lug stereo jack (tip, ring and sleeve) rather than a standard two lug one. The negative terminal of your battery should be wired to one and the other should go to the preamp somewhere.

Bassist on the Run Posted November 14, 2023 Author Share Posted November 14, 2023 I’m gonna have to take to a bass wizard to fix up. There are more cables in there than a telephone exchange 😂 I’ll keep this post posted with an update. Appreciate any messages I’ve had. Thanks people👍 Quote Link to comment Share on other sites More sharing options...
