I picked up one of these used last year and it sounds awesome, it has worked great at practice, but I have had it shut down twice at gigs when turning it up. After searching the web, it sounds like this is a common problem, earlier units were having problems with the fan, which may have caused earlier issues. My fan works, but it still shuts down when I start to push it. It seems like others have had this problem. I have contacted Rocktron and I'm waiting to hear back. I have a feeling these issues are why they stopped making this amp and are making the Mainline 300 instead now.
