Used Catalinbread FORMULA NO. 5 Overdrive Pedal

This Catalinbread Formula No. 5 captures the raw, touch-sensitive character of a small, cranked American-style tube amp in pedal form. Designed to deliver dynamic breakup and harmonically rich overdrive, it offers simple controls for volume, tone, and gain that make it easy to dial in everything from gritty edge-of-breakup textures to thick, saturated drive. The compact enclosure and straightforward layout keep the focus on feel and tone rather than menu diving.

Catalinbread voiced the Formula No. 5 to respond closely to picking dynamics and guitar volume changes, making it especially expressive under the fingers. The gain structure emphasizes clarity and punch, allowing chords to stay defined while single notes bloom with sustain. It is a favorite among players looking for vintage-flavored drive tones that feel amp-like and organic rather than compressed or overly polished.
