The Green Rhino Overdrive Mark IV has more force than ever behind its mighty charge, featuring the Volume, Tone, and Drive controls of the original with the MKII's 100Hz, an all-new 500Hz control, and a Classic switch to get the simple Volume, Tone, Drive setup and sound of the original Green Rhino Overdrive.

This pedal can be powered by a 9-volt battery, a Dunlop ECB003 9-volt adapter, or the DC Brick™, Iso-Brick™, and Mini Iso-Brick™ power supplies (not included).
