Friday night our band had to cancel a gig at the last minute because of, IMO a design flaw with the casters on the Cyclops. We were setting up a couple of hours before we were to play and my amp falls over and lands on the lead singers foot and puts him in the hospital. Broke his foot!! What happens is when you pick the amp up to set it on stage the casters will drop down a little and stay that way when you set it back down. This makes the amp uneven and the Cyclops being so top heavy anyway will fall over. This has happened several times with me but I was able to catch it in time. Friday night someone else put it on stage and wasn't aware of the problem and thats when the singer got sucker punched by my amp. This is the first time in 32 years I have had to cancel a gig at the last minute and it really stinks. Saturday morning the first thing I did was yank the amp out of the combo and put it in a rack mount case. Not sure if I will ever use that cabinet again but the R600 amp is still good. Anyway all you Cyclops owners be careful if you have casters on your amp.
