AC-40 Roland Acoustic Guitar Amplifier Output: 35W Includes adapter and bonus case Please consider this if you are looking for AC-33, AC-60, etc. I purchased this used and used it about 3-4 times a month for about a year and a half. The adapter (Roland) was purchased new. I used it, but all functions worked without any problems. Please understand that this is a used item and has been inspected by an amateur. Please refer to the photos for the exterior condition. I purchased a case that seemed to fit and used it, so I will include it as is. I plan to ship via Rakuraku Mercari. Thank you very much. - Brand: Roland - Design: Black color - Speakers: Front speakers
