The English Muff'n Pedal from Electro-Harmonix is a vacuum tube distortion/preamplifier pedal designed to enhance your music and expand the range of your existing equipment. The English Muff'n is used to create the sound of 1960s British guitar amplifier's pre-amp and tone circuits. The English Muff'n consists of both a gain stage and a tone control section. The tone control section contains high (treble), midrange, and low (bass) tone controls, which form a traditional "tone stack," as used in vintage pre-amp sections of '60s British guitar amplifiers. A "tone-stack" refers to how an amplifier is voiced for EQ and Gain in the pre-amp section. All three EQ controls are interactive, letting the player dial in anything from hard-driving modern distortion to the sweet sustain of classic vintage models. The pedal is supplied with two Electro-Harmonix 12AY7 tubes.
This pedal features five knobs. The Gain knob controls the intensity of the drive and will provide a stunning range of overdrive selections. The High knob determines the treble response, which tailors the attack and enhances the harmonic content of the pre-amp. The Mid knob provides the key to an impressive range of distortion tones. The Low knob controls the bass frequencies, giving a range from thuddy and heavy to tight and punchy. The Volume knob determines the overall output level and amount of boost.
