I had quit using my LSS for gigs because of a problem that was intermittent. I took my amp in to the local Mesa dealer and they swapped out a tube that I had replaced a week earlier. Anyway, that didn't solve the problem.
I spent a lot of time with Mesa's tech support and got nowhere. I was stuck!
Long story short, turns out that it was the speaker! After playing at moderate volumes for a couple hours, the voice coil would catch making it sound like you were using a fast kill switch in and out. Kind of a machine gun effect. I used one of my Mesa ext. cabs and the problem was solved.
Now the amp is out of warranty so I need to buy a new speaker, but at least I have the problem solved.
I've never heard of a problem like this before. "Most peculiar mama"
