Electro-Harmonix Small Stone

The Electro-Harmonix Small Stone, introduced in 1974, is a legendary analog phaser pedal that has become a classic for its lush, swirling modulation effects. Designed by David Cockrell, the Small Stone was Electro-Harmonix's response to the popularity of the MXR Phase 90, offering a deeper, more dramatic phasing effect. It features a simple Rate knob to control the speed of the modulation and a Color switch to adjust the depth and feedback of the phase effect. The pedal's warm, vintage tone and versatility have made it a favorite among guitarists, bassists, and producers across genres.

Historical Development

• Release and Features: The Small Stone uses OTA (Operational Transconductance Amplifier) chips for its phasing circuit, giving it a distinctive low-mid "swoosh" and rich harmonic texture. Early models (1974–1978) featured the EH1048 OTA chips and were housed in a durable "big box" enclosure.
• Revisions: Over the years, the Small Stone has undergone several updates, including changes to its circuitry and enclosure size. Modern reissues retain its analog warmth while improving reliability.
• Impact: The Small Stone quickly became a competitor to other phasers of its era, offering unique tonal characteristics that distinguished it from rivals like the MXR Phase 90.

Notable Players

• Kevin Parker (Tame Impala): Frequently uses the Small Stone for its lush modulation on tracks like "It's Not Meant to Be," often with the Color switch engaged.
• Dimebag Darrell (Pantera): Used it to add movement and texture to his iconic metal tones.
• Steven Wilson (Porcupine Tree): Known for employing it in his ambient and progressive rock soundscapes.

Popular Settings

The Small Stone's simplicity allows for a range of creative applications:

• Subtle Modulation: Rate at 10:00 with Color off for gentle background movement.
• Classic Swirl: Rate at noon with Color on for rich, deep phasing ideal for rhythm or lead parts.
• Psychedelic Vibe: Rate at 3:00 with Color on for fast, dramatic modulation reminiscent of Leslie speaker effects.

Its warm analog tone, straightforward controls, and ability to produce everything from subtle modulation to dramatic sweeps have ensured its place in music history. Despite competition from other classic phasers, the Small Stone's unique character continues to inspire musicians worldwide.
