This moog 12 stage phaser is in mint condition and perfect working order. Purchased in 2008. This is what Moog had to say about it:

Your MF-103 is a direct descendent of the original Moog™ modular

synthesizers and professional rack effects. It contains two complete modular

functions: a 6-stage/12-stage voltage-controlled Phaser, and a voltage-

controlled wide range Low Frequency Oscillator (LFO). All four performance

parameters are voltage-controllable, which means that you can use expression

pedals, MIDI-to-CV converter, or any other source of control voltages to 'play'

your MF-103.

While you can use it on the floor as a conventional effects box, your MF-103 is

much more versatile and its sound quality is higher than the single fixed-function

"stomp boxes" that you're probably accustomed to. You will find that your MF-

103 is a deep musical resource. It will give you an amazing variety of new

sounds and will become your creative companion as you explore its functions.
