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. All Stomp Under Foot pedals are made by hand and use only quality, through-hole components. • MFSKU Silver Foxx
