From the post
Info about the original:
Mark Sullivan from daddys.com wrote this
The Mudhoney is a Distortion/Fuzz pedal with a very wide tonal range. It features a typical 3-knob gain/volume/tone layout plus a boost switch. I played this for a few minutes with the boost off and it is quite impressive; very thick tone with warmth that could quickly find its way to being your main dirt for jazz, blues, etc. Then I pushed the boost and cranked up the gain! The speakers in my little Princeton cried for mercy. Hitting it with the bridge pickup of a Les Paul brought sustain of Spinal Tap proportions. Chords were a menacing wall of sound but yet unlike its name would imply, the Mudhoney didn’t get muddy and muffled. Note and harmonic separation was impressive giving a very dimensional sound at gain levels where most pedals sound flat.
Features
This baby is designed for those who want an in-your-face wall of guitar sound jumping of the speakers.
The boost button and the tone knob enable you to dial in every sound you like right from ultra fuzz to smooth jazz sounds.
In "OFF-MODE" (with the boost-function bypassed) the Mudhoney delivers moderate gain and a smooth rich sound favoured by many jazz-guitarists. For a more hairy sound, -just hit that "boost-button" and feel the rumble from hell.
The BOOST button switches between moderate- and high gain.
The GAIN knob controls the distortion amount.
The LEVEL knob sets the overall volume In mid-position (twelve o’clock) the volume level is 1:1. When turned full over (clockwise) the input signal is boosted 15dB.
The TONE knob affects the top end (edge) of your signal without compromising sonic quality, allowing you to dial in the perfect tonal flavour for you taste.
(Edit on 2023/01/03 - Note that there has been a new version of the traced schematic and we have a layout for it here. It may or may not sound closer to the original Mudhoney.. Read more about it on FSB / Miro)
