A silicon transistor fuzz from Wren and Cuff, known for recreating traditional fuzz sounds! The gain is low, giving it a thick sound with clear mids. The tone changes very little with the gain knob, so it can be used like an overdrive with good volume sensitivity. Your Face Smooth Silicon 70's Fuzz produces an incredibly smooth, high-gain 70's Fuzz Face sound. There's no other fuzz pedal that's as easy to use and smooth as this one. - Uses two carefully selected BC108 transistors with specific gains - Ultra-low noise metal film resistors - Added capacitors for easy-to-handle high frequencies and to prevent unnecessary feedback at loud volumes, creating a smooth sound - Supports high volumes - Equipped with a reverse log pot for fine tuning the fuzz sound - Uses Mullado tropical fish capacitors for improved low-frequency clarity - Low-Cut knob allows for fine adjustment of low end and sustain It can be powered by a 9V DC center negative adapter (One Control EPA-2000 is recommended) or a 9V battery.
