Roland AC-33

Super Portable, Versatile, Battery-Powered Stereo Acoustic Guitar Amp

Rich, deep, stereo sound to go — introducing the AC-33, the world’s first 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.
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.

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.

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.
