Here's my story: I bought a Bongo back in January of this year from Musician's Friend. It came looking brand new - all tags were still on and it doesn't appear to have been a return. As can happen in shipping, the bass shifted enough to bend the volume knob. I got a replacement pot from EB and went and had it put in at a local shop (which I've been going to for 14 years and trust). Before I took it in to have the pot replaced, I played it maybe two hours tops plugged in. Both batteries installed were Duracells. I don't remember if I replaced them right away, but things sounded normal and not like the batteries were low. So I had the repair work done, plugged it in and played an hour or so more with it. Then because of various other things I had going on, I haven't touched it since mid-January. it's been sitting in the case all this time. I take it out last night, and I get nothing when I plug it in. I start freaking that the work wasn't done right replacing the pot, even though I know it was working when I left the shop. I try a different bass on the same rig to verify it's the Bongo, which it is. Then I have the bright idea of checking the batteries. I put two fresh ones in, and sure enough, everything is fine. Just to confirm both batteries were dead, I tried them one at a time in my Stingray, and I got nothing with each of them. So here's my question: could the repair person have done something to either drain down the batteries or cause the circuit to always be on? I've been playing active basses for 15 years, and I have NEVER had fully dead batteries in a bass. I suppose it could have come with low batteries from the factory, but even still, I would have expected to go through a period of bad sound before no sound. Any thoughts on this are appreciated - for now I guess I'll have to get a battery tester and check them daily to see if they are draining when I am not using it.
