Roland Ac-33

The World's First AA Battery-Powered Acoustic Guitar Amp - Rich, deep, stereo sound to go - the AC-33 is the world's first AA battery-powered amp made specifically for acoustic guitar. Portable yet powerful, the AC-33 provides true stereo sound, Guitar and Mic/Line channels, custom-tailored effects, anti-feedback, and a Phrase Looper.

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. 

 

Natural, Stereo Sound

Equipped 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 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

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.

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.
