This was an updated version of the original PH-1. It had an additonal “Resonance” knob (feedback control) to increase the tonal variations. This is a 4 stage phaser like the PH-1 and its biggest competitor at the time, the MXR Phase 90. It can create an wide array of different tones.
The PH-1R has all of the features of the clean, low noise PH-1 plus a Resonance control for added depth of phase. A Rate control provides more sweep speed variance than any other phase shifter now available – from 100msec to 16 seconds – while the Depth control, permits notch depth adjustment, adjusts the phasing intensity and tailors the PH-1R to whatever instrument is being used, resulting in more precise control over virtually any creative application. A deeper-sounding phase effect can be achieved be rerouting the previously phased signal back through the circuit by means of the Resonance control. This control is adjustable over a wide range in order to permit maximum creative control.
