Versatile, full of features, big sound yet incredibly compact weighing in at only 5.3Kg, the Roland AC-40 acoustic chorus guitar amplifier is a perfect companion for gigging guitarists and singer/songwriters. Perfect for home, studio and intimate gigs, the AC-40 offers superior projection of both guitar and voice thanks to its dual channel inputs.

Room-filling audio

A pure and natural sound comes as standard with the AC-40 as part of the acclaimed acoustic chorus series. Vocal mics, guitars and other acoustic instruments shine through from the dual speakers and to really give your sound that extra polish, you can add stereo chorus and reverb, providing studio-quality depth and dimension that you simply can't achieve with mono counterparts.

The big sound of the AC-40 can be pushed as much as you want, thanks to the anti-feedback. This comes in handy especially if you're playing in confined spaces. With the simple flip of a switch, you have the freedom to relax and concentrate on performing without worrying about unexpected sound hassles.

Ideal for voice and instrument

With its two independent channels, the AC-40 gives you pro versatility for any performing setup. There’s a dedicated guitar channel with a standard ¼-inch jack input, plus a MIC/LINE channel with an XLR/TRS combo input for connecting a microphone or a line-level device. Plug in a guitar and a mic for self-contained playing and singing, or use the channels to mix two types of pickups (or a pickup and a mic) in more sophisticated guitar rigs. Each channel has its own three-band EQ for sound shaping plus independent chorus and reverb controls, giving you complete command over your sound.

Finally, add to the already impressive array of features of the AC-40 aux-in and line out connectivity, headphone jack and pedal socket for easy on/off switching of effects and you have the complete, portable package for your acoustic performance needs.
