Electro Harmonix English Muff’N

Electro Harmonix English Muff’N is vintage “British” vacuum tube pre-amp. This uniquely powerful tool is 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 amp’s pre-amp and tone circuits. Please take a few minutes to familiarize yourself with the English MUFF’n controls and how they work.

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 amps. 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.

As in the classic British amplifiers, the sweetness and power of the tone is a combination of working the preamplifier gain against the Post gain. The more you turn up the preamplifier, the more saturation of the tubes there is. This results in anything from a sweet and subtle blues overdrive all the way to the classic British stack cranked to the max.
