ok, i've had my roadster combo for about a year and have had two problems, but both were not really the amps fault. First problem was when the soundman used a 200' extension cord to hook me up and the fuse blew (which was only a 3 amp fuse that long and mcquade had in the amp instead of a 4 amp), second time was when we were playing an outdoor gig and they were powering us off a generator which kept cutting out, its been in the repair shop for almost three months since then waiting for the parts from mesa since they won't let them use just anything in the amp, fortunately with the warranty, long & mcquade has given me a loaner amp the whole time at no charge so i'm not completely ****-out-of-luck. I always gig with a (solid state) backup and bring spare fuses and tubes, just in case, cause with a tube amp, you never know what might happen. that being said, i love the roadster and even with these two mishaps, i wouldn't trade it for any other amp. I usually keep my reverb down low anyway so there's no issue there, and the popping goes away after a few channel changes in standby. bottom line, you can't go wrong with a roadster!
