Roland's compact AC-33 stereo acoustic guitar amp runs on AC or AA battery power, so you can truly take this big-sounding 30-watt (20 watts on battery power) rig anywhere you play. Its dual-channel configuration means you can plug in a mic and your guitar, turning this amp into a true mini PA! The AC-33 also includes reverb, chorus, and ambiance effects. You even get a handy phrase looper, which gives you 40 seconds of recording time. Plugin your favorite music player, via the auxiliary input. Set up wherever you want, pop up the built-in tilt-back stand, and express your acoustic side through the AC-33.
