Discontinued. Great condition, great effect, just not getting the use to justify keeping it. Some creasing to the box. Any questions please ask.

From the manufacturer:

MF Ring is an analog ring modulator, based on the best-selling Ring Mod in the world, the MoogerFooger MF-102.

The unique tone voicing circuit of the MF Ring adds a new musical dimension to ring modification, making it easy to dial in everything from octaves and choral dissonance to harmonic undertones and synthesized lead lines.

The expression pedal input provides hands-free control of the Freq control for sound sweeps, pitch shifting effects and playing between two scales on the fly.

Each Minifooger stomp box is housed in a rugged cast aluminium enclosure, featuring an 100 analog signal path. The true bypass design pedal is hand-assembled in Moog's factory in North Carolina and features optional battery power and a single expression pedal input that can also be controlled via CV.
