The Electro-Harmonix English Muff’n is a tube-driven overdrive/distortion pedal crafted to deliver the iconic British amplifier tone of the 1960s and ’70s. Powered by real vacuum tubes (dual 12AY7s, user-upgradable to 12AX7s), this pedal provides an authentic warm and dynamic tube preamp saturation that ranges from smooth, subtle overdrive to rich, all-out distortion.

Featuring intuitive controls for Volume, Gain, and a three-band EQ (High, Mid, Low), the English Muff’n allows precise shaping of your tone, making it versatile for blues, rock, and heavier styles. Its robust build ensures reliable gig-ready performance, while the true bypass switching preserves your signal integrity.

Known for its ability to emulate the classic British rock and blues tones, this pedal has been a favored choice for players seeking vintage tube amp character in a compact pedal format.

Powered by a 12V DC supply, it fits effortlessly into any pedalboard setup and delivers lush, warm harmonics and dynamic response impossible to get from solid-state pedals.

A perfect tool for guitarists longing for a piece of British rock history with modern flexibility and reliability.

Tape on the charger. I've found great tones from mixing and matching valves, they don't need to be matched, you can put a 12au7 into a 12ax7.
