Master Volume not working.

[domct203]

.........
That is what bugs me. You pay all the money for this amp and one of the greatest features is the channel assignable power and yet you cant use it as intended because of the popping.

And this helps the OP how?

The popping the OP was talking about is when he puts the amp into standby and has nothing to do with channel switching.

Hi. My first post on the forum.

My Mesa Mark V has a problem:
The main master on the amp doesnt change volume at all. When I turn it it does nothing. It was ok a week ago but this problem just started this week. Also when I click in to Standby the amp makes a loud pop.
The individual channel Masters work though.

Any suggestions on what might be causing it would be appreciated.

Even if it was about channel switching/power settings, I still don't see how any of your posts would have helped ......... It really looks like you are trolling.
