Our users rate Reverb
For sale is a Maestro PS-1A Phase Shifter, a classic vintage analog modulation unit from the 1970s, designed by Tom Oberheim and originally built in the USA.
This is a simple but highly musical three-speed phase shifter, offering Slow, Medium, and Fast modulation settings with the distinctive smooth, swirling character that made early Maestro phasers famous.
A true piece of vintage studio and guitar history, the PS-1A is known for its rich, organic phase tones and natural ramping effect between speed changes, delivering everything from subtle movement to deep, rotating-style modulation.
