The Roland AC-33 is the world's first battery-powered amp made specifically for acoustic guitars, which provides a deep, rich stereo sound on the go. Portable yet powerful, the AC-33 provides true stereo sound which can be tailored to fit your exact specifications so you can find your voice. Guitar and Mic/Line channels allow for further expressive control, and when paired with the reverb and chorus effects, anti-feedback as well as the on-board phase looper - you'll find a truly unique sound which can be shaped and re-shaped time and time again.

Made to go to places no amp has gone before, the AC-33 is loaded with both an AC power input and AA battery powered capabilities, meaning that wherever your musical journey takes you, this amplifier is right there by your side. What's more, none of the tone is sacrificed through the addition of this innovative feature, and you'll be sure to find a glorious amplified acoustic voice full of tonal depth and clarity.

Innovative acoustic technology

Equipped with Roland's latest DSP technology, the AC-33 amp, 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 Sing

The 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 Looper

The AC-33's onboard Phrase Looper lets you record, loop, and jam over your own guitar riffs or incoming audio from the AUX input. Record and loop up to 40 seconds at a time, and amaze your listeners with sound-on-sound performances that you create on the spot.
