Pigtronixs ALL NEW Philosophers Rock ! – Pigtronix Philosophers Rock is a streamlined version of our award-winning Philosophers Tone pedal. The Philosophers 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. 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. – – Goto Product!
