Catalinbread Formula 51 Overdrive

Introducing the Catalinbread Formula 51 overdrive, a powerhouse pedal that brings the classic tone of a tweed Champ amplifier to your pedalboard. With its rich harmonic content and dynamic response, this pedal captures the essence of vintage tube-driven overdrive. From smooth and creamy blues tones to crunchy rock and roll grit, the Formula 51 delivers versatility and character. 

The Catalinbread Formula 51 features a preamp, a discrete power amp simulator and an output transformer to deliver the full touch-sensitive Tweed experience, with a grip of extremely interactive controls. The Sag control loads down the transformer to your taste, giving you some real-deal blown-out leads with the twist of a knob. The Tone control is straight out of the vintage amplifier playbook, incorporating the mid scoop control of the Framus Cobra amp. This time-tested mod essentially turns the mid-leaning Tweed profile into the mid-scooped “blackface” sound of later Champs. Run it at 18V for more headroom!
