Hi Dave (your email bounced),
I hope you’re well and safe down in LA. My mom lives down there and I know a lot of people being affected.
This weekend I encountered a problem with my Memphis. When I switch to the lead channel, it’s incredibly noisy with white sound, the gain volume goes from zero to explosively loud and the master volume doesn’t do anything (it’s like it’s bypassed).
Knowing nothing about amps, I suspect it may be a preamp tube problem?
The rhythm clean channel seems to be working just fine. And after initially discovering the lead channel problem, I switched back and forth and at one point the lead channel was working again as it should. But after about a minute, it almost blew my head off with the white noise background and gain volume basically full on when it’s not at zero along with an ineffective master.
What are your thoughts?
