The Electro-Harmonix Small Stone Phase Shifter is a 4-stage phase shifter pedal first made in 1974 by David Cockerell with the legendary operational transconductance amplifiers (OTA). Along with a Rate knob, the Color switch is used to engage an additional stage of feedback for a more pronounced phase shifting effect.
