The Guyatone PS-019 Phase Shifter is a rare vintage modulation pedal from Japan, produced in the late 1970s to early 1980s. Known for its lush, swirling textures and smooth, organic movement, the PS-019 delivers the kind of classic analog phasing that defined many psychedelic and progressive rock recordings of the era. Built with sturdy Japanese craftsmanship, it remains a sought-after piece for collectors and players who appreciate unique vintage tones.
Controls include Rate, Depth, and Feedback, allowing for a wide range of phasing effects. Rate sets the modulation speed, Depth controls the intensity of the sweep, and Feedback enhances the resonance, producing everything from subtle movement to deep, resonant phase sweeps. The warm analog circuitry gives the PS-019 a distinct character, often described as richer and more musical compared to many modern phasers.
Guyatone, one of Japan’s pioneering pedal manufacturers, earned a reputation for building rugged and innovative effects, and the PS-019 exemplifies this heritage. Compact, reliable, and sonically distinctive, it is a vintage modulation gem that continues to inspire musicians today.
