I love the feature set that comes with this amp. It has everything needed to really shape your tone to your own personal liking.
The only thing I would have liked to see was a headphone jack. The portability of this amp is amazing but you cannot practice with it silently in your hotel if you are on the road. Its a very small amp, but i think they could have thrown it on the back somehow. another thing would have been a multi speakon that accepts a 1/4 inch as well as the speakon.
also a little more power would have been a tad better. Maybe 600 watts. its pretty loud but it does have its limitations.
Tone is its best asset though. That plus the weight. Overall I love it enough to have bought a second amp.
