But this amp was made to go places no amp has gone before. Thanks to its battery-power capability, the AC-33 lets you take your act anywhere into the backwoods, onto the streets, or wherever your imagination leads you. * 30 watts (15W 15W) of natural, stereo acoustic sound through twin speakers * Runs on AC power or eight AA batteries (or AA rechargeable Ni-MH batteries) * Dual-channel configuration: Guitar and Mic/Line channel * Reverb, chorus, and ambience effects (Ambience adds spatial, 3D-type depth to the sound) * Phrase Looper with 40 seconds of record time * Stereo AUX input (connect MP3/CD players, etc), headphone output * Anti-feedback function * Built-in tilt-back stand * Removable battery cartridge for easy battery replacement Natural, Stereo SoundEquipped with Roland s latest DSP technology, the AC-33, delivers pure, rich acoustic sound with projection far beyond its size. Its true stereo design (15 watts x 2) enables brilliant stereo/multi-band chorus with Wide mode, plus shimmering reverb and 3D-type ambience effects tailored specifically for acoustic guitar.Strum and SingThe AC-33 provides two discrete channels: Guitar and Mic/Line. Plug in an acoustic guitar and a microphone (or line-level instrument) and mix them separately. Both channels have dedicated controls for volume, multi-band EQ, and chorus. The Mic/line channel offers both XLR and 1/4 inputs. You can also connect an MP3/CD player to the stereo AUX input for play-along practice or performance. Master volume, reverb, ambience, and anti-feedback are provided as well.Phrase LooperThe AC-33 s onboard Phrase Looper lets you record, loop, and jam over your own guitar riffs or incoming audio from the AUX input.
