Legacy of Excellence
The AC-90 isn’t just any new amp on the block … it’s the long-awaited addition to Roland’s industry-leading AC-series amp family. Roland’s reputation for world-class sound, amazing performance, portability, and top-quality construction in the AC series are all upheld in this stunning new amplifier.

In addition to its amazing acoustic-guitar amplification qualities, the AC-90 can also function as a portable PA system thanks to its dual-channel architecture, sub output and phantom-powered Microphone input. Sing and play guitar through one convenient amplifier, with impressive power and full-range performance.
With 90 watts of stereo power (45W+45W) driving top-quality speakers, the AC-90 delivers exceptional full-range performance — from shimmering, crystal-clear highs to full-impact bottom end. This amp is more than capable of cutting though a wall of sound.
