Electro-Harmonix Small Stone (1974)
A 4-stage analog phaser pedal first made in 1974. Known for its sweeping phase tones and the "Color" switch.
Overview
The Electro-Harmonix Small Stone is a 4-stage analog phase shifter pedal. David Cockerell designed it at Electro-Harmonix, and it was first made in 1974 in New York City. It has since become a classic in guitar effects. The "Rate" knob sets the speed of the phase effect. The "Color" switch changes the sweep, and the down position is noted for a fuller sound. A later version, the Small Stone Nano, runs the same circuit in a smaller chassis.
