The Dunlop JH-OC1 Octavio pedal beautifully recreates an iconic Jimi Hendrix sound as heard on "Purple Haze" and "Fire." This octave fuzz was designed after careful dissection and analysis of JImi's original octave-up pedal and uses the same circuit layout to nail its incredible sound. Simple as can be with just two controls and an on/off switch, the Dunlop Octavio is built like a tank and sounds like a tank that's on fire.
