The Philosopher's Rock pedal by Pigtronix includes a myriad of effects in one small stompbox. Marketed as a compressor/sustainer but capable of totally wild distortion, the Philosopher's Rock is immensely versatile. This streamlined rendition of the Pigtronix Philosopher's Tone boasts 4 times the compression range of its older brother as well as a "Grit" switch that engages Germanium Distortion. Able to provide a wide range of compression tones, a crystal-clear sustain, and gritty distortion in one, the Philosopher's Rock deserves a spot on your pedalboard.

    I picked this up for next to nothing on a whim. I just needed something inexpensive for my bass board. This was also my first optical compressor, and it's as smooth and quiet as advertised. Grit switch is a nice touch, and offers some seriously raunchy distortion. However, I knocked off a star for not having a separate switch to engage it. The toggle isn't useful live.
