Founded by Mike Matthews in New York City in 1968, Electro-Harmonix became known for inventive effects that brought new sounds within reach of guitarists. Its first product was the LPB-1 Linear Power Booster; the company’s long-running catalogue ranges from fuzz and overdrive to delay, modulation, octave and experimental processing. JustPedals listings include the Small Clone chorus, Small Stone phaser, Memory Boy delay, POG 2 octave generator and Micro Q-Tron envelope filter. Check the exact version and power requirements when comparing EHX models, since familiar names often span different generations and formats.

Tremolo varies amplitude, making volume rise and fall; vibrato varies pitch, making the note move sharp and flat. Some circuits combine both or derive them from modulation systems that blur the boundary. Rate, depth, waveform and stereo phase determine whether the motion is smooth, pulsing, choppy, seasick or spatial, while tap tempo can lock the cycle to a rhythm.

The signal is shaped by continuously varying electronic circuitry rather than being converted into a digital effect algorithm. Component choice, operating voltage and circuit tolerances influence headroom, noise, clipping texture and the small variations in response between designs.
Creates one or more time-separated copies of the signal. Delay time sets their spacing, feedback determines how many repeats continue, and filtering, modulation or saturation decides whether successive echoes remain clean, darken, wobble or break apart.
