For sale we have a Pigtronix Philosopher's Rock Compression/Sustain/Distortion pedal in good used condition and perfect working order. The pedal shows some light cosmetic wear with some scuffs in the finish on top as well as some remnants of adhesive on the bottom plate from previous velcro mounting. Aside from that the pedal works and sounds fantastic. Features an impressively wide range of compression, controls for Volume and Sustain, unique optical circuit gives you transparent compression and endless sustain. Engage the 'Grit' switch for germanium distortion. 9V-18V option allows for greater headroom. Will be professionally packed with care and shipped priority within the continental U.S. Thanks for looking.
