Comments about Roland AC-33 Acoustic Chorus Combo Amp:

Basically just what I was hoping for. It's not cheap and the bass response is a tad lacking, but for it's size, it does a great job of representing an idealized acoustic guitar sound. The reverb and chorus is adequate to quite nice. Plenty of volume for coffee house gigs, busking or using as a monitor while feeding the PA. I actually use it with the Roland Micro Bass RX. I take the mono line level output of the AC-33 and feed the input of the Bass RX. This takes me to the sound I want, particularly when playing a baritone or pentatonic guitar (discontinued Schecter Celloblaster). I have always achieved my acoustic sound with bi-amping and now I can do it with portability -and not have to worry about noisy power sources! Negatives: be better with a protective grill instead of thin cloth in front of the speakers. Wish there was a separate reverb level for vocal and a delay effect. Be nice to have a send and return for both instrument and mic input -particularly for the mic input.
Overall... you can get more for your money if you don't need battery operation and the small size, but otherwise, this is the best game in town. I have no buyers' remorse whatsoever.
