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.
