Mesa Nomad Huge Hum
Okay, I just got my new Mesa Nomad today...sounds AMAZING, very versatile, and an incredible clean channel. Channel 3 is excellent for rhythm, and I am still working on a great lead sound from Channel 2..
Anyway, on to my question/problem:
When turning the master volume on either Channel 2 or 3 up past 9 o'clock, I get a SUPER loud hum. Even when the master volume (output) is all the way down, there is a ton of hum still present. That is with the guitar volume and the output all the way down. Any suggestions? I think it might be a bad preamp tube, but I'm not sure.
We basically for tonight turned the master volumes for each channel down to about 3 and cranked the output...sounded VERY sweet, but you could smell the tubes cooking...and I don't want to have to replace tubes constantly, so I was wondering if anyone had a suggestion on how to take care of this hum problem?
