WORKING CONDITION: Excellent. This phaser has a very low noise floor when idling - excellent for recording. All modes work properly and the sound is thick and lush.

PHYSICAL CONDITION: Very Good. The chassis and orange paint are still in very good condition, and the foam pad on the bottom of the pedal is still intact. This pedal was well cared for over the past 50 years.

PRODUCT DESCRIPTION: This listing is for a Vintage MXR Phase 100 Effects Pedal w/ Original Box & Manual. 

The vintage MXR Phase 100 is a 10-stage analog phaser first introduced in 1975. Known as the "big brother" to the Phase 90, it features a more complex circuit that can produce everything from subtle shimmers to deep, flanger-like "growls" and Uni-Vibe textures. Unlike the single-knob Phase 90, it includes a four-position Intensity rotary switch that selects between different preset waveforms and regeneration levels.

SPECS:

• Serial #  7-027760
• Circuitry: 10 stages of all-pass filters using vactrol (light-dependent resistor) technology.
• Controls: Speed (knob) and Intensity (4-way rotary switch).
• Power: Original vintage units run on a single 9V battery only - no power supply facility on this unit.
• Current Draw: Low, typically around 6 mA
