Electro-Harmonix Small Stone

Analog phase shifter

The Electro-Harmonix Small Stone is an analog phase shifter first designed in 1974 by David Cockerell. Built around operational transconductance amplifiers, it is a four-stage phaser with a single Rate control and a Color switch that adds feedback for a deeper, more resonant sweep, giving the rich, swirling phasing heard across decades of records.

    Electro-Harmonix (EHX) is an American maker of effects pedals for electric guitar and bass, founded by Mike Matthews in 1968 in New York City. An early pioneer of affordable stompbox design, the company is best known for the Big Muff Pi fuzz, along with influential models such as the Small Stone phaser, Memory Man delay, and Electric Mistress flanger. After closing in 1984, the brand was revived in the 1990s and continues to design and build a broad pedal range in New York.
