I've had this amp for over a year now and I absolutely love it. It's built like a tank but looks great, and the sound is incredible, both the on the guitar and the voice channel. I generally don't like plugging in because the quality of my Martin D-18's sound always seems to suffer compared to when it's miked. This amp makes it sound both full and bright, with absolutely no artificial overtones. It's also great on the voice channel; I've always been a somewhat insecure singer but this amp makes my voice sound good, even to my hyper-critical ears. This amp sounds so good that I'd actually rather plug in, even at home, just because of the quality of the sound.
