90 watts in a lightweight package
With 90 watts of stereo power (45W+45W) driving top-quality neodymium 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.

Anti-Feedback
Enjoy maximum volume without feedback, thanks to the AC-90’s sophisticated ANTI-Feedback feature. This allows you to roam the stage with confidence — even with 90 watts of powerful sound at your back.


Stereo effects
The AC-90’s onboard stereo effects benefit from Roland’s decades of research and development. Experience the amazing spatial depth and lush sound of the stereo multi-band chorus, complete with newly developed WIDE mode. Delay and reverb are provided as well, and can be controlled via footswitch.


Also functions as a PA
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.
