i have a rocktron rampage RT122C and against all odds i really like this amp with my guitar and effects..but occasionally the stupid volume will kick in and out...it usually goes back to normal after i unplug it for a while and seems to only do it after extended playing...but what happens when i gig it? can i fix this?
If it is attatched to an amp and doesnt go shred...what...what the hell is it?? Eww..
I don't know anything about this amp so bump for ya.

If it is a tube amp or has power tubes, then I suspect the power tubes need to be replaced.

If it is a solid state amp, then I suspect the volume potentiometer (pot) is acting up and needs to be replaced. That could be true with tube amps too.
