Effects Bakery's Cheeseburger RE9V Battery. This is a rechargeable 9V battery, purchased new a few years ago at an Ishibashi Music store. I kept it as a spare for when my effects pedals' batteries died, but I never used it, so I'm decluttering. It works without any problems. ▪︎Contents ・Battery body ・Original case ・Original snap cable ・General-purpose USB cable (not originally included with the product) Please check websites like Soundhouse for information on usage, etc.
