Sing and play guitar through one convenient amplifier, with impressive power and full-range performance.

Loaded with high-performance neodymium speakers and 90 watts of power, the Roland AC-90 amp provides a rich, powerful sound while remaining lightweight for easy transport. The AC-90 employs a stereo 2-way speaker system that delivers transparent highs -- great for the built-in multi-band stereo chorus -- while also providing incredibly powerful low-frequency performance.

Legacy of Excellence
The AC-90 isn't just any 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 amplifier.

Power Performer
With 90 watts of stereo power (45W+45W) driving top-quality neodymium speakers, the AC-90 amplifier 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 Control
Enjoy maximum volume without feedback. Simply dial in the offending frequency and the AC-90 will suppress the feedback. This allows you to roam the stage with confidence -- even with 90 watts of powerful sound at your back.

Immersive Stereo FX
The AC-90 amp's onboard stereo effects benefit from Roland's decades of industry-leading R&D. Experience the amazing spatial depth and lush sound of the stereo multi-band chorus, complete with developed WIDE mode. Delay and Reverb are provided as well, and can be controlled via footswitch.

In addition to its amazing acoustic-guitar amplification qualities, the Roland AC-90 can also function as a portable PA system thanks to its dual-channel architecture and phantom-powered Microphone input.

  • AC 90 Step up

    As reviewed by Frank Grimaldi on 2/13/2008

    I just purchased an ac 90 a couple of weeks ago. I had been using an ac 60 for the past few years and loved every musical minute of it. Carry it on stage, line out to mixer, monitor back just perfect. Two guitars, two separate EQs one main mixer channel, how easy is that. Take it into a church one channel for vocal other channel guitar just an amazing sound. A couple of months ago my nephew (Dave) tells me Rolands come out whith a ac 90 little bigger spearkers with tweeters and a bit more power. Seemed to good to be true. Just when you think you've heard the best,the best gets a little bigger and better. Now Dave gets the ac 60 and i get the 90. Thankyou Roland

  • Great Amp

    As reviewed by Royce on 12/16/2008

    I've been trying to play my Martin D15 through bass amp, regular guitar amp, and even a keyboard anp. Even when using the LR Baggs M1A acoustic pickup, I could not get the tone I was looking for. That is until I purchased the AC90 acoustic amp. I am absolutely pleased with the sound. One of the other reviews mentioned adding a sub-woofer. That's got my curiosity up, so I will try that in the near future. I don't use a lot of effects when playing, but when I do, this amp provides a quality chorus and reverb that meets my requirements.

  • Excellent acoustic amp for classical guitars

    As reviewed by Angel on 8/31/2011

    I have used the Roland AC60 for about 2 yrs and the sound was outstanding, considering the small size of the unit. I switched into the Roland AC90 recently to provide a wider spread of the sound as well as a little more crisp sound out of my nylon strings flamenco guitar. The bigger 8 inch woofer speakers as well as the added tweeters makes a wider and greater difference in the sound. When properly adjusted, this amp can give you a nice quality sound in a small package. Very practical to carry the unit due to low weight and case included. Highly recomended.
