OK i got the RL1000 head,, i always run it with input gain at 0, both power amps at 5 and the master volume at about 1.5-2 for jamming with my drummer. NOW i have to turn the master volume up to 4 or 5 to keep up!! whats up with this?? Did the amp go into "shutdown" mode or what? I should mention that I first noticed it a couple days ago,, thought it would go back to normal but it hasnt!! Any suggestions would be appreciated!!
