The Boss PH-1r Phaser was a revision of the original Boss PH-1. The PH-1r is a standard 4 stage phaser that was produced to emulate the swirling tones of the popular Leslie style rotating speaker cabinets without needing a specialised speaker setup. Users of the PH-1 were happy with it's tone but thought it lacked the throbbing tremolo-style phase that other pedals could produce (due to the PH-1's low internal feedback setting). Boss revised their flagship phaser with a resonance (feedback) control to give the user more control over this aspect.
The Rate knob adjusts the speed of the phase, the Depth knob controls the intensity of the effect and the Res (or Resonance) knob controls the feedback of the phase.
Produced from October 1980 until May 1985.
The printing of the PH-1r had 2 variations. The earliest models feature a larger model number, which placed the P in PH-1r under the S in Phaser. Later versions shrunk the logo, placing the P in PH-1r under the E in Phaser.
Good vintage cosmetic condition, works perfectly. Serial number 069200.
