Bad Cat Hot Cat ?

[chuckb]

Hey guys, I've been having a strange problem with the gain channel on my Bad Cat Hot Cat build. It seems everytime I plug into the gain ch my vol pot on my guitar becomes scratchy whenever I turn it up or down. At first, I thought it was the volume pot of my guitar but when I plug it into the clean ch it's fine. I tried another guitar and it does the same thing. Any ideas what it could be? Faulty input jack maybe? Any help would be greatly appreciated.

Chuck.

Sounds like a small amount of DC showing up on that particular jack. Try swapping out the tube tied to that jack.

Man, those amps eat tubes like crazy.
One customer has two of them, it seems like I'm always replacing tubes in it.
