Any Genz Benz Shuttle 3.0 Issues ?

Hi , looking at pulling the trigger on a cheap 3.0 , I know they are good wee amps but would they do a 5 hour gig without any heating issues bearing in mind they dont have any fan cooling ? , should I look out for a 6.0 instead ? Thanks

GB are very reliable amps and backed by great customer service. I have used my 3.0 for a few years now without problems.
