I don't currently play much bass since I play regular guitar in the project I'm currently in. Since we don't have a bassist at all right now, we have a pedal that plays the backing tracks that include the bass and we plug it into my bass rig, which is an Ampeg SVT-450 and two 8 ohm cabs. Several years ago the gain knob got knocked off, leaving the metal underneath, and since I consider it mostly cosmetic and don't change the gain when playing actual bass guitar, I never replaced it. But we've had to change the the gain more often since we play the pedal though it. During the last month or so, every time I try to change the gain while the amp is on it delivers a shock that while all it does is jiggle my elbows and piss me off, I don't like playing around with any electrical shock and I'm aware of the possibility that it could get worse. I've even experimented with using a different amp and another outlet in the same room, and the same thing happens. I had an electrician look at it and he replaced one of the outlets, but I'm not sure he fixed it because I think he probably just saw that it was upside-down (with the ground prong on top) and replaced it. I tried testing the ground with a multimeter and it seemed fine, but I'm inexperienced and learned to do it from watching a tutorial, and I'm not sure I did it right. I also tried using the hot multimeter probe on the gain knob to see if it picked anything up, and it stayed at zero. This issue is just weird to me because my guitar amp has never done this, just both bass amps. And it seems to only happen when it has been on for a little while and is quite loud. Also when we don't have the pedal, I plug in my laptop, and I get shocked through the keyboard! I have not yet taken my amp to a technician, but that will be the next step. Also, the house was built in the '40's. I'm guessing grounding may have been different then. Thoughts are appreciated!
On a side note, when I first got this Ampeg the fan would not turn on, but from suggestions on this forum I was able to fix it since the fan connector turned out to be plugged in upside-down. I'm super grateful for that help, and I hope for more of the same! Thanks!
