ZOOM MULTI STOMP MS-50G. Functionality has been confirmed. Both battery and adapter power work without issue (photos 2 & 3). Box, manual, and warranty (unfilled) are included. This item is in excellent condition, having only been used a few times indoors. It has not been stepped on. This model is still popular because it has preset tones that are unique to it. Apart from a few minor scuffs, it's in like-new condition. The inside of the box has some slight staining. Please check the photos for details. Although it's in excellent condition, it is a used item, so please refrain from purchasing if you are overly concerned about minor imperfections. Please read my profile to avoid any potential issues. Thank you very much.
