The AC-40 Acoustic Chorus Guitar Amplifier is the latest addition to Roland’s popular line of AC stereo acoustic guitar amps. Weighing in at less than 12 pounds (!) the AC-40 uses dual custom-designed 6.5-inch speakers to project massive sound throughout the room. Onboard footswitchable stereo chorus and reverb effects add studio-quality depth and dimension. Dual input channels provide a dedicated guitar input as well as a mic/line input; each channel has independent 3-band EQ and chorus and reverb controls, while an anti-feedback function automatically controls acoustic feedback problems on stage. A stereo aux input supports music players, and line out jacks and a headphone output increase versatility.
