True-Bypass 9V Battery or 2.1 9V Adapter Only 2mA NOS Parts Handmade in the U.S.A. Based on the 1971 Foxx Tone Machine, the Silver Foxx retains the same thick fuzz the originals are known for. The gain control can go from a warm overdrive to full-out, massive, fat fuzz that gives you thunderous chords and sweet lead tones. The tone control was modified for a fuller sweep from high to low and there is a little more gain on tap. The octave is accessible by a separate foot switch and uses NOS germanium diodes to create screaming leads and ring-modulated chords. The original pedal came covered in a velvet-like material so I had the Silver Foxx pedals powder-coated in a crushed velvet finish. Stomp Under Foot pedals are made by hand using only quality, through-hole components.
