Description

Boss PH-1R Phaser – 1981 MIJ Early Production Silver Screw Black Label

Condition

This PH-1R Phaser is in Very Good condition. Build date of February 1981 making it very early production. There are small, scattered chips and scuffs on the exterior. Prior signs of corrosion in the battery cavity have been cleaned up. The original silver screw to close the pedal/battery cavity has been replaced with a later black knob version. However, the serial number and case design indicate that this is an early silver screw version of the PH-1R. The deteriorating rubber screw gasket has been replaced with a new one and the unit has been thoroughly cleaned. The pedal has been tested with a 9v battery and compatible power supply. All functions are operational. The original packaging and instructions are not included. This unit requires a BOSS ACA power supply or a 9V battery.
