Roland AC90 45/45 90 Stereo Watts Performer Amplifier in Excellent shape hardly used never gigged with. I think this would work fine in a restaurant/bar 75 to 100 people maybe more, certainly depends on the type of setting per how loud the audience is. Has onboard effects like reverb and chorus and channels for vocals and guitar to be performed at the same time. Somewhat light weight and easy to transport. I toured many years as a professional musician and thus purchased this amp but found the scene to be unacceptable to bother with performing out. Time to let the amp go to someone who might actually use it. Have another Roland AC60 hardly used for $400.00 30/30 60 watts stereo, same relative amp but smaller with carry case. I also have another listing of a nice Cole Clark Acoustic Guitar with electronics that works well with these amps. Please check them out.
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.
Versatility
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.
