Similarity
citedBlended from circuit-archetype lineage, dynamic feel, tone-signal overlap and tone-vector distance — the tone vector itself is derived from editorial description text, not a measured acoustic signal, so this reflects how similarly the catalog copy describes the two, not a lab measurement. Shown only within a gear class, and only where there's enough evidence to be meaningful.

Description

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.

The Catalinbread SFT Ampeg Inspired Overdrive is a version of the Portland boutique builder's SFT pedal, capturing the tone and feel of a vintage Ampeg tube amplifier front end. The circuit delivers warm, harmonically complex overdrive with an American vintage character drawn from the Ampeg amplifier tradition. Like other SFT variants, it works with both guitar and bass, producing organic saturation ideal for blues, studio recording, and roots music. Controls include gain, volume, and an amplifier-style tone stack for shaping the vintage American character.
