Robert Keeley began by modifying effects for guitarists and built the first Keeley Compressor while pursuing more useful control over dynamics and sustain. The Oklahoma City company now designs, builds, tests and refines its effects there, with a range spanning compression, overdrive, fuzz, pitch, delay and reverb. The Compressor remains its best-known family. JustPedals listings also include the Mk3 Driver, Octa Psi pitch shifter and fuzz, Manis overdrive and Nocturne reverb. Keeley’s work often adds practical controls to familiar circuit ideas, such as pickup-sensitive release settings on its compressor pedals.

Chorus mixes the dry signal with one or more short, continuously modulated delays. The small pitch and timing movement between the paths creates width, shimmer and the impression of several instruments playing together. Rate controls the modulation speed, depth controls its excursion, and delay or mix settings determine whether the result is subtle thickening, a liquid wobble or a broad stereo image.

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.
Combines the dry signal with a very short, modulated delay. Regularly spaced phase cancellations form a moving comb filter, while feedback intensifies the notches and resonance to produce anything from gentle motion to a metallic jet-like sweep.
