Zoom's vocal effects processor, the V3. It's a beautiful item with little use. There were originally no included accessories, and I used it with batteries. You can also use the official adapter if you purchase one. ★Operation confirmed (no problems) ★Includes new AA batteries When cleaning with alcohol, the serial number bled and became unreadable, so I removed the label. Please be aware of this. Instant purchase welcome. #zoom #vocal effects processor #effector #V3
