Description
The Boss PH-1 was the original phase shifter made in Japan by Boss with a simple two-knob control. It was succeeded by the PH-1R with added resonance control. This is a very early example of a Boss classic. This pedal sounds absolutely lucious and magical with its glorious swirling tones. It's got that subtle, three-dimensional warmth that later PH models don't seem to have. Silver screw, Made in Japan serial 9400
