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.
