The TONE CITY AUDIO Mad Stone Fuzz is a compact pedal that delivers rich, vintage-style fuzz with the smooth character only germanium transistors can offer. Known for their warm midrange and responsive dynamics, germanium circuits give the Mad Stone a classic, rounded tone that stands out with every note. Need more bite? Kick on the octave-up function to add a searing high-octave layer that cuts through the mix with ease—perfect for bold solos and standout riffs. Plus, with true bypass circuitry, your core tone stays untouched when the pedal’s off. Please note: This pedal is not compatible with 9V batteries and must be powered using a 9V DC power supply.
