Keeley Electronics

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.
