Re: Three bad pots in a row?

OK, sorry for the slow update... I got a set of caps and installed them and this significantly reduced the noise. I went ahead and replaced the pot as well because with all the trial and error, it was pretty abused. I soldered the ground to the shaft washer as mentioned above. Also, I yanked the bat...

Re: Three bad pots in a row?

I did not make the PUs myself (which is why one would make the buffer circuit? or else I've got more serious issues than I thought...). They are Schaller S6's. I've got no electrolytic caps in my meager stash. If there's still a Radio Shack open around here I may be able to get some tomorrow, otherw...

Re: Three bad pots in a row?

David; I grabbed my multi-meter and checked the battery first, just for reference: 8.77V. I plugged the guitar in to the amp and checked the volume pot. There is most certainly a DC voltage across it. I read a voltage drop across the volume pot that varies from 0 to 9, depending on the volume settin...

Re: Three bad pots in a row?

Best practice is to solder the case ground wire to the lock washer that goes under the pot. That's an awesome idea, I think it's exactly what I'm looking for. Seems obvious after you mention it. Daryl, the lugs you mention look handy, I'll probably make one until I get to a point where I think I mi...

Re: Three bad pots in a row?

Here's the schematic. That's not a good representation of the switch- it's a 3-position switch that turns on one PU, or the other, or both. I've been tweaking it, it's a work in progress, but this is where it's at now:

Re: Three bad pots in a row?

I'll get a schematic up shortly... They are active pickups, so there is a battery involved. Also, there's a very good chance that I overheated the first one. I tried to take better care on the second, and on the third I used alligator clips to try to eliminate overheating as a cause. I've also grabb...

Three bad pots in a row?

Hello all... Not sure if this is just bad luck or if I'm doing something dumb. I wired a guitar and it had a noisy volume pot. I lived with it for a while since it was fine as long as you didn't move it. It just made noise while it was being turned. Something came up and I needed it fixed on short n...
