Request. As everyone knows this is Mike Fuller's version of the Fuzz Face, but it has something that we haven't included in the multitude of Fuzz Face layouts we have on the site so I thought it was worth adding a mojo layout. Sticking two fingers up at convention Mike called what most would consider to be the bias pot "Contour", and a pre-effect level control "Bias". So just to confuse matters further the trimmer which biases Q2 is part of the Contour circuit (doh!). But they all make things sound a bit different so you can call them what you like I suppose.

This is a positive ground effect which can't be daisy chained with your run of the mill negative ground pedals, so consider including the negative voltage inverter circuit to provide the -9V which will make this daisy chain-able (is that a real word?). That is my favoured way by far to deal with positive ground effects because it also allows you to use the much more consistent PNP transistors and so not have to take a gamble of hit and miss NPN germaniums.

Info from Mike about his original:

This is how you wished your Fuzzface sounded... Fat and Harmonic. And it cleans up like a vintage Fender amp when you turn down your guitar's volume control. The Rolling Stones and the Black Crowes have discovered this trick.

If you love the first 2 Hendrix releases then you'll love this pedal, with 2 Germanium transistors hand-picked and tested for optimum performance. A Contour Knob lets you dial in Midrange, Harmonics and Sustain, also an Input Bias knob that takes out the "woofiness" and gives great Overdrive/Distortion sounds when its level is reduced. An Internal Trimmer allows for adjustment of Clipping Symmetry, Harmonics, and Tracking.

Specifications subject to change at any given moment due to availability... and whimsy.

Alrighty then ...
