Electro Harmonix

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.

Octave Pedals

An octave effect generates notes one or more octaves above or below the input. Analogue circuits often create raw monophonic sub-octaves, while digital pitch tracking can follow chords and provide several intervals with cleaner separation. Tracking speed, polyphonic accuracy, latency and the balance of dry, upper and lower voices determine whether the result feels tight, organ-like, synthetic or deliberately unstable.

Bass

Voiced or equipped to retain low-frequency fundamentals and the higher headroom of a bass signal. Clean blends, crossovers and bass-specific filter ranges can preserve weight and articulation while the effected portion adds harmonics, movement or ambience.

Distortion

Clips the waveform firmly and adds a dense series of harmonics with compression and sustain. The clipping devices, gain stages and tone filters determine whether the result is tight, smooth, mid-focused, scooped, grainy or deliberately abrasive.

Fuzz

Pushes the signal into extreme clipping, often approaching a square wave and producing dense harmonics. Transistor type, bias, input loading and filtering govern whether the texture is smooth, woolly, gated, spluttering, octave-rich or highly responsive to the instrument volume.
