The Philosopher's Rock features Pigtronix’s unique optical circuit that provides transparent compression with endless clean sustain. This all analog, state-of-the-art dynamics processor is further augmented by a harmonic germanium distortion that can be added via toggle switch for even more over-the-top tones that will instantly melt faces when engaged. Many top slide guitarists have gravitated towards the Philosopher’s Rock due to its distortion characteristics being remarkably similar to the “tube rectifier sag” of a small amp being mercilessly overloaded.

Although the Philosopher’s Rock has fewer controls than its more knobby siblings, it actually sports a 4 times wider range of compression tones on tap. This allows the Philosopher’s Rock to be used as a more subtle, clean compressor as well as a super squashy sustain machine when maxed out. The Philosopher’s Rock can be used to tame peaks in your signal as well as to create natural acoustic feedback with or without distortion. Super low noise performance allows the Philosopher’s Rock to be effective in front of a dirty amp or combined with high gain distortion and fuzz pedals for crafting your personal wall of sound.

The Treble and Blend functions from the original Philosopher’s Tone have been preset to the “sweet spot” for hassle free operation on stage or in the studio. The Philosopher’s Rock features true bypass switching and runs fine on standard 9-volt (negative tip) power but ships with an 18-volt adapter for superior headroom, clarity and overall output.
