Adding an active/passive switch to a Bartolini TC3 Jazz Bass Specific Harness?

    So, my '78 Jazz has a battery box route, that for some stupid reason I don't want to leave empty. I had an Audere in it, then an East J-Retro, and then (and currently) another Audere. I love both those preamps, but I kinda want just a traditional Jazz bass setup without the EQ. I want to hear the pickups as they were originally intended to sound. Problem is, I'm used to loud, HOT pickups and these vintage 78 J pickups are just a lot quieter than what I am used to. I don't want to swap them out because they're the original pickups (I think.) So here's a perfect solution:


    It's Bartolini's TC3 booster, which basically just gives the boost of a preamp without the EQ. It's already wired to a Jazz plate, which is great. Minus one thing I want - an on/off active/passive kill switch in case the battery runs low. I imagine adding one of these would be fairly simple. Anyone tried it? I'm wondering if I could drill a little hole in the plate and add a switch? Or better yet, change one of the pots (probably the tone pot) to a push-pull and then set it up so that it disengages the preamp when you pull up on the pot.

    Anyone tried this? I assume it would be relatively easy? I'd probably have a local tech do it since I am technically inept.
