The Catalinbread Formula No. 55 is an amp-voiced overdrive pedal from the Portland boutique effects builder, designed to capture the tone and response of specific vintage amplifier settings in the tradition of their Formula pedal series. Like other Catalinbread Formula pedals, it models the circuit behavior and harmonic characteristics of a target amplifier front end rather than functioning as a generic drive pedal. It delivers warm, natural saturation with the feel and dynamic response of a pushed tube amplifier. Suited for blues, classic rock, and studio players seeking an authoritative amp-in-a-box overdrive tone.
