So I was selling a bass last night. I went to play it while the guy was on his way - no sound. I panic for a minute 'til I realize not only is it an active, but remember I left it plugged in overnight a couple days ago. Sure enough, dead battery, voltmeter at 1/2V. Can't find a new one, so I had to pull one out of another bass, voltmeter says 8.2V. All is well. I'm playing it as the guy pulls into my driveway, no problems. He comes in, starts to play it, and after about 10 seconds it starts putting out a horrible noise. Trade the cord, the noise is still there, notice that the noise alters when touching one of the three knobs, the one that is a stack knob (thank goodness it wasn't my amp). This bass has been fine since I got it, no kind of problems, and this guy has just driven 45 min. and the bass decides to crap out. I feel like an ass. So we open the control cavity to see if there's anything obvious, but with the preamp circuit and lots of rainbow colored wires, neither of us see anything that might be a problem. Put it back together, fire it up, noise is gone! BUT the top knob (midrange) doesn't work at all. Ouch. I can't believe the Murphy's Law timing, and I don't think draining a battery the other night could have caused the pot to go wacky, but I look like I'm trying to pull something on the guy. Luckily the guy loved the blue burst and insane birdeye on the neck (it is a very pretty bass) and took it anyway, but I had to knock $70 off my asking price. Says he has a good tech. I figured that if I had to keep it I'd hafta take it to a tech, at some cost/time, etc., not worth my hassle. But why couldn't it wait a day to start freaking out? or 15 minutes even?! Must be the curse of having traded away a great G&L for this thing in the first place. Good riddance.
