Electro-Harmonix Small Stone (1974)
A 4-stage analog phaser effect pedal first made in 1974, known for its sweeping phase tones and iconic "Color" switch.
Overview
The Electro-Harmonix Small Stone is a 4-stage analog phase shifter pedal originally made in 1974 by David Cockerell at Electro-Harmonix. It was manufactured in New York City and has since become a classic in guitar effects. The pedal features a "Rate" knob that controls the speed of the phase effect and a "Color" switch that alters the character of the sweep, with the down position noted for delivering a fuller sound. A later version, the Small Stone Nano, replicates the same circuit in a smaller chassis.
