Used Catalinbread Formula 55 Effect Pedal

Used Catalinbread Formula 55 in great condition delivers the touch-sensitive growl and sparkle of a classic late-’50s American tweed amp in a compact pedal. Dial in everything from edge-of-breakup warmth to rich, harmonically complex overdrive with intuitive Volume, Gain, and Treble controls. Built for standard electric guitar signal chains, it runs on a 9V DC center-negative power supply and features true bypass switching for a clean, unaffected tone when off.
