The Pigtronix Philosopher's Tone is a state-of-the-art analog compressor / sustainer, providing endless clean sustain. With variable Sustain (threshold), Blend (ratio) and Treble controls, the Philosopher's Tone offers a huge range of compression sounds for the discerning musician. The Philosopher's Tone also contains a smooth diode clipping distortion with a blend control for clean or dirty compression sounds and any mixture of the two. While the Philosopher's Tone distortion rocks on its own, it is designed to play well with other dirt pedals in order to create your ultimate distortion tone that sustains forever. The Philosopher's Tone is an ideal front end to any guitar pedal rig and a perfect companion to the Pigtronix Mothership Guitar Synthesizer or any other pitch-tracking musical equipment, resulting in even more accurate tracking and increased note duration. Unlike the many compressor clones and their variations that have become so popular in the past 10 years, the Pigtronix Philosopher's Tone is not based on a CA3080 chip. This pedal has more sustain and less noise than any of those outdated, over-hyped devices. The dynamic range, touch sensitivity, overall transparency and outright sustain of the Philosopher's Tone is un-paralleled in the crowded world of compressor pedals. Pigtronix adapter included.
