AC-90
Acoustic Chorus Guitar Amplifier
THE ARRIVAL OF A FUTURE CLASSIC
The highly anticipated addition to Roland’s AC-series amp family has arrived! Loaded with high-performance speakers and 90 watts of power, the AC-90 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.
