The JHS Firefly is a tribute to the classic Tonebender MKIII fuzz pedal from the late 60s. This three-transistor Germanium fuzz features Volume, EQ, Fuzz, and Bias controls for versatile tonal shaping. The EQ control cuts highs, while the Bias control fine-tunes the power to the hand-matched germanium transistors for dynamic, temperature-resistant fuzz tones. Use the Firefly for classic fuzz tones and boost applications similar to a Tonebender.
