I have a Pedulla 6 string active bass with Bart pickups and preamp that was built in 1993. I've had this thing since this summer, and every once in a while the output on the bass will suddenly drop and the tone will become fuzzy, static-filled, distorted... however you want to describe it. The first time this happened I replaced the battery and the problem went away for a while. However, just a few weeks later, it started happening again intermittently.
I took it to a local repair tech, and he ruled out that there was a short in the jack draining the battery. He did say that the output jack was pretty worn and not making a very solid connection due to its age, and he wanted to order a jack in and replace it.
It was going to take too long to get the part in so I took it to another local luthier/repair tech (who is pretty well known; I know a few people on TB have his basses). He pointed out that there were some bad solder spots inside and some of the wires had worn through their insulation. He replaced the output jack and did a complete rewiring and resoldering job on the bass. Problem solved, or so I hoped.
Last night I accidentally left the bass plugged in overnight. When I got it out this morning to practice a little before work, I noticed that it was doing it again. I replaced the battery with one that had been used, but only for a short time. When I plugged it back in again, it sounded distorted, but after about fifteen seconds it cleared up. I thought everything was good until I sat down to practice tonight and it was distorting again.
I've emailed Pedulla to see if this is a problem he's had before, and after I hear back from him I'm probably going to talk to the luthier again and see what he can do for me. I was hoping that maybe you guys would have some ideas or suggestions for me. Here's a YouTube clip of the actual sound
. The video was taken on my phone, but the sound IS an accurate representation of the phenomenon. This is probably the worst that it has ever sounded. It's not this bad right now, but if I don't get this sorted out then it may end up this bad again. Please don't judge my playing.
