Blended 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.47% — somewhat different

The Browne Amplification Protein V3 is a boutique dual-channel overdrive pedal handbuilt in Montreal, representing the third version of the dual Carbon and Gritador circuit. The Carbon channel delivers a transparent, Bluesbreaker-style low-gain overdrive and the Gritador channel a mid-forward, Tube Screamer-influenced drive. Each channel has independent gain, volume, and tone controls alongside a three-way mid-shift toggle. The Protein responds like a tube amp front end, cleaning up naturally with guitar volume. Popular with blues, indie rock, and country players seeking organic dual-channel foundation overdrive.
The Catalinbread Formula 51 is a Fender amplifier-inspired overdrive from Portland, Oregon, part of the Formula series that captures the tonal character of specific Fender amplifier designs. Like the Formula 55 and Formula 5F6, the Formula 51 extracts the warmth, bloom, and harmonic character of a Fender amp driven naturally, with the specific voicing and response of its inspiration circuit. Covers the range from clean boost through warm, organic overdrive with natural compression and American amp character. Made in Portland by Catalinbread.
