The Dunlop Jimi Hendrix JH-FI Guitar Effect Pedal is a loyal reproduction of the legendary Fuzz Face pedal used by Jimi in the late 60s. While the original Fuzz Face knobs and finish give it the look, the hand wired circuitry in this guitar pedal can also reproduce some quality vintage fuzz tones. This guitar pedal even allows you to create octave tones and mix the two, giving you a more versatile sound. The Dunlop Jimi Hendrix JH-FI Guitar Effect Pedal is built around BC108 silicon transistor, providing you the power to recreate the authentic sound of classic Hendrix guitar effects.
