One of the most unique and recognizable phasers ever made. 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.
This (in)famous phaser shows signs of age and use but this is all cosmetic. It functions great and is ready to have another go at it on your board. It ships the next day.
