Just purchased this amp in the last year however it has proven to be very a versatile amp for me. Being a guitar player in Rock cover bands it allows me to cover all basis...Classic Rock, Modern Rock, Grunge, Alternative etc. Only issue I have with the amp is the annoying popping sound when switching to channel 3 and Mute/Tuner for the first time after power-up. If you're amp is at gigging levels this could be a very loud pop which would probably be bad for the ears not to mention the equipment.
Overall I'm very satisfied with the amp.
