This is a Jimi Hendrix System Classic Fuzz made by Jim Dunlop. It was part of a series released in the 1990s, and this model reproduces the sound of the Fuzz Face used by Jimi Hendrix in a compact size that's easy to incorporate into a pedalboard. Sound Characteristics: It uses silicon transistors and features the edgy, aggressive fuzz sound heard in Jimi's later career. It also responds well to guitar volume adjustments, and the clean-to-crunch texture when the volume is rolled back is a unique charm of this model. Rarity: Unlike the current round Fuzz Face and Mini series, this JH-2 with its square enclosure is no longer in production, and many enthusiasts are looking for this as a vintage Dunlop from the 90s. It combines a rugged look with a practical size. Condition: The exterior shows signs of wear and tear commensurate with age, but there is no significant damage. Other: This listing includes the main unit only. It operates on a 9V battery or a standard AC adapter (center negative). Please understand that this is an older product before purchasing.
