The AC-40 is an amplifier for acoustic guitarists, with a rich, warm sound that brings out the best in your guitar. As part of Roland’s Acoustic Chorus family, the AC-40 delivers clean, loud, and natural sound for acoustic guitars, and you can also add a microphone, making it ideal for singer/songwriters.

Onboard stereo effects include a high-quality digital reverb along with Roland’s famous chorus sound, while the anti-feedback function automatically reduces acoustic feedback, so you can concentrate on your performance. Weighing just over 5kg and with extensive connectivity options, the AC-40 is the perfect companion for acoustic musicians on the move.
