PS1 Phase Shifter

The DeltaLab PS-1 Phase Shifter is a compact analog modulation pedal that offers classic four-stage phasing effects. It features straightforward rate and depth controls, allowing musicians to create everything from gentle, subtle movement to more pronounced swirling phase textures. Produced in Japan during the early days of compact pedals, the PS-1 is recognized for its warm modulation character and simple signal path. Its design draws from the phaser circuits popular in the late 1970s and early 1980s, making it a versatile choice for both guitar and keyboard players. Production of this model has been discontinued.
