Hello, Yesterday, I played a gig with several other bands. I am friends with many of the other musicians, and so I volunteered my Genz Benz Series 2/Avatar 212 for common use. When my band went on, I noticed that the levels were set rather high, and so I turned down. Early on in our set, I started noticing that both the preamp and the poweramp were limiting frequently, so I turned both the gain and the master down further. I thought I was fine, but then the amp started cutting out...I looked back, and it was going into thermal shutdown. Our set was almost over, so I put both the gain and the master at 8:30 and finished playing. Today, I tried playing through the head, and both the preamp and the poweramp clip if the gain is higher than about 9 o'clock. I was using a passive, fairly low-output bass with no effects, and this does not normally happen. Any ideas as to what might have happened? I'm well aware that I made a number of possibly poor decisions, from letting people use the amp to finishing the set. Does it seem to you that it this is something that would be cost-effective to fix? If a repair will be expensive, it might be in my best interest to just purchase a more powerful amp. Sorry for the length of the post, and thanks for any advice!
