Roland AC-33M Battery-Powered Stereo Acoustic Guitar Amplifier with Phrase Looper, Dual Channels, DSP Effects, and Portable Design for Acoustic Performance (AC-33M)

Product Description:
The Roland AC-33M is a versatile battery-powered stereo acoustic guitar amplifier designed to deliver rich, natural acoustic tones anywhere musicians perform. Combining Roland’s advanced DSP technology, true stereo amplification, dual input channels, onboard effects, and a built-in Phrase Looper, the AC-33M provides a complete portable solution for acoustic guitarists, singers, and performers.

Featuring a 30-watt stereo amplifier system with two 15-watt channels, the AC-33M produces a wide and detailed acoustic sound through its twin speakers. Roland’s stereo processing delivers enhanced depth with multi-band chorus, reverb, and Ambience effects, creating a spacious 3D-like sound field that brings out the natural character of acoustic instruments.

The amplifier includes separate Guitar and Mic/Line channels, allowing musicians to perform with both an acoustic guitar and microphone or line-level instrument simultaneously. Each channel features dedicated volume, EQ, and chorus controls, while the Mic/Line channel provides both XLR and 1/4-inch input options for flexible connectivity.

For creative performances, the built-in Phrase Looper allows players to record and layer guitar phrases or audio from the AUX input for up to 40 seconds. This makes the AC-33M ideal for solo performances, practice sessions, songwriting, and live looping applications.

Designed for maximum portability, the AC-33M can operate using AC power or eight AA batteries, including rechargeable NiMH batteries. Additional performance-friendly features include an anti-feedback function, stereo AUX input for external audio playback, headphone output for quiet practice, a built-in tilt-back stand, and a removable battery cartridge for convenient battery replacement.
