Formula 51

The Fender Formula 51 is a versatile amp-in-a-box pedal that emulates the classic Tweed Champ sound. Designed to capture the essence of the iconic 5F1 circuit, this pedal can produce a wide range of tones, from clean and gritty to substantial mid-heavy distortion. Musically, the Formula 51 responds dynamically to your playing style, allowing for expressive touch sensitivity. Its Sag control adjusts the load on the transformer, providing a range of lead sounds, while the Tone control enables a mid-scooped profile reminiscent of later blackface models. For added versatility, the pedal can be powered at 18V for increased headroom, making it suitable for stacking with other effects.
