Analog Phaser
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.
Version Differences
The earlierst versions the P in PH-1R was located under the s in Phaser. Later the font was slightly changed and the P was then found under the e i Phaser. This change happened around serial number 14xx00. The early PH-1R’s with 4 digit serial numbers had a silver thumb screw instead of the later black screw.
