My 100 Watt Marshall MA100C is plenty loud enough for gigging, but is a bit heavy to lug around, I alleviated that a bit by installing four Casters on it so that I only have to pick it up when carrying it down a flight of stairs, I had a 5 Watt Legacy Valve amp but apparently it got stolen from the music department at Uni some time last year, the little 5 Watt Pitbull Guitar amp looks like it might be a good replacement for it, hence the reason why I'm very much interested in getting one once they become available.
