The Moog Moogerfooger MF-103 12-Stage Phaser is a robust analog phaser that delivers rich, dynamic sweeping effects. Its rugged design, complete with classic Moog aesthetics, offers a 6-stage/12-stage phaser with stereo outputs, making it versatile for various audio applications. The inclusion of CV/Gate control adds flexibility for integration with modular setups. However, its mono input might be limiting for some users, and the lack of MIDI support could be a drawback for those seeking modern connectivity options. Overall, it's a great addition for those seeking authentic analog warmth and motion in their soundscapes.

Lush, vintage-sounding OTA phaser with insane CV modulation capability.

Lush, liquid, vintage phaser. The input drive stage sounds good enough to use on its own, especially on drums. Turn the sweep off and resonance down, and use the main + aux outs to stereo-image a part to make it stand out in a mix. Extensive CV implementation. Using the sweep in jack, you can modulate 6 of the stages independently of the other 6 -- making it capable of Mutron Biphase emulation (a highly sought-after phaser used by Lee Scratch Perry among others.) Eliminated my phaser lust and stopped me having to build a Haible Krautrock phaser or Mutron clone. Hainbach on Youtube has a great video on pinging it for percussion sounds with the SQ-1. Can run up to 15v for increased headroom. Plans to make a eurorack jack field panel so I can patch it easier, otherwise you need a fistful of 1/4" to 1/8" cables or adapters. Really glad I bought one of these while they were still being made -- Moog discontinued all their pedals as of 2019 :(. Expect them to be outrageous on the used market!
