PRODUCT DESCRIPTION
- Click on the link below to view a detailed Brochure on the Roland AC-33. Natural stereo sound The Roland AC-33 Acoustic Chorus Amp is equipped with Rolands latest DSP technology - it 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 & sing The Roland AC-33 Acoustic Chorus Amp 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 Roland AC-33 Acoustic Chorus Amp was made to go places no amp has gone before. Thanks to its battery power capabilities the AC-33 lets you take your act anywhere - into the backwoods onto the streets or wherever your imagination leads you. The AC-33s 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.
