【Product Description】 Roland Mobile AC, with original box and manual This is a Roland Mobile AC. Compared to the standard model, this version is set up for acoustic guitars. After purchase, it was used mostly indoors with very little outdoor use, and I haven't used it much recently. I'm selling it because I won't be using it anymore. Operation has been confirmed using only batteries. ●Important● This is a private sale, so there is no warranty. Please understand that this is a used item and purchase it as is.
