The Way Huge Green Rhino Overdrive MkIV takes a legendary overdrive circuit and expands its tonal flexibility without sacrificing the character that made it a favorite among players. Alongside the familiar Volume, Tone, and Drive controls, dedicated 100Hz and 500Hz EQ controls allow you to precisely shape your low end and midrange, while the Classic switch instantly recalls the straightforward voice of the original Green Rhino. From transparent edge-of-breakup tones to punchy rhythm sounds and sustain-rich lead tones, the Green Rhino MkIV delivers exceptional versatility with the warm, dynamic response that has defined this iconic overdrive for decades.

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.

The Green Rhino™ Overdrive Mark IV is smaller and more compact than its ancestors, but it has more force than ever behind its mighty charge. In addition to the Volume, Tone, and Drive controls of the original, this beastie has the MkII's 100Hz control and an all new 500Hz control so you can to cut or boost your lows and mids by 12dB each way. Make your notes shake the ground like a stampede across the savannah or cut through the mix like a rushing rhino's horn. Want to take this pedal back to its ancestral roots? Just throw the Classic switch to get the simple Volume, Tone, Drive setup and sound of the original Green Rhino Overdrive.

The MkIV is as versatile as it is rambunctious, and it'll come to heel if need be. It can take a clean amp from pristine purity to a punchy, dynamic rhythm tone, but put it in front of a distorted channel, and you'll hear more gain and sustain than you ever thought your amp was capable of.

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).
