ENGLISH MUFF’N
Vintage “British” Vacuum Tube Pre-Amp
Congratulations on your acquisition of the Electro-Harmonix English MUFF’n, our
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.
It is easy to set up the Muff’n to give you that sweet Brit sound with an emphasis of
any part of the EQ curve. For example, dipping the midrange produces the classic
scooped sound. As always, experiment to achieve your own unique sounds. For the
first time, you really do have the classic British sound. It is totally dependent on the
vacuum tubes. No modeling, no DSP, just the classic sound, which was totally created
by vacuum tubes just like the originals.
GAIN – This controls the intensity of the drive and will provide a stunning range of
overdrive selections. Lower settings will give a simple volume boost, while advanced
settings will yield screaming solo sounds.
