RG75 G3 problem!

[Addaam]

When I turn up the amp, it cuts out. It has to be considerably loud for it to do it, like to be heard well over a drumkit, but still not up full. So I was wondering if anoyone here has any idea on what the hell's going on, if it happened to them. I'd really like not to have to take it in to a place for repairs...

My Rh150G3plus does the same thing. I changed it to a new one because the problem was there when I first time tried the amp.

I don't know, the new one has the same problem. I'm just going to ignore it. I'm tired to wait a new one so... If you find out what is the problem then post it here. This sucks..
