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.

Specialist Effects Pedals

Specialist effects alter the signal in ways that do not sit cleanly inside one established family. They may use granular processing, frequency shifting, resonators, freeze or sustain, bit reduction, ring modulation, feedback networks or combinations of several techniques. The relevant distinction is the underlying process, its tracking or latency, and how completely the dry signal can be blended or replaced.
