First just to say that I have had no problems whatever with the fan noise that others have mentioned - I suspect DV Mark has fixed this problem.
I play an electric mandolin in a group with drums, piano, bass, guitar, saxophone, trombone and clarinet - which is to say loud - and this amp has no problems being heard. I've also had lots of compliments on the tone it produces.
It is easily carried - neither too bulky nor too heavy. It has controls for bass, mids, treble, master volume and reverb - no gain, let alone things like chorus or simulations. Not a problem for me - I like the clean jazz tones and am only too pleased to keep things simple when setting up.
