OK all, some of you know of my 5E3 Trepidation Amp build. So I have been enjoying the tar our of it lately and have noticed something. When I have the volume of Volume 1 past 5 I get a pretty good hummmm, hiss out of the speaker. But when I roll back the tone it pretty much goes away. So I have been playing through channel 1 and rolling the tone back to eliminate the humm/hiss. So yesterday I am messing around and decided to try to play with channel 2s volume while I was playing through channel 1 as everyone says it affects the tone. So channel 2 was set at 8 on the dial. I played a chord, had hiss and humm and then rolled the volume back on channel 2 and it decreased the humm/hiss to nothing. With the volume up on channel 1, volume all the way down on channel 2 I get a just a touch of humm, but when I run volume 2 up the hum increases although I am playing in channel 1. Do I have a faulty pot or a bad ground on pot channel 2? I have checked all the other grounds and I should be good but this hum persist.
