Featuring a parallel circuit design of three JFETs, a four position resonance switch and triple drive pot section, the Fairfield Circuitry Four Eyes Crossover is built to run the fuzz gamut from vintage germanium to RAT-esque silicon. Housed in a die-hard steel chassis and versatile enough to go from a garage setup to metal chug, this box of fuzzy goodness pulls quadruple and can easily replace multiple fuzzes on a board.
