Legendary synthesizer manufacturer Moog announced today the discontinuation of the oft-beloved “Little Phatty” synth, created in 2006 as a tribute to the life and legacy of founder Bob Moog.

In a short documentary released today and embedded above, Moog Music president Mike Adams, Chief Engineer Cyril Lance (the designer of the Little Phatty) and Product Development Specialist Steve Dunnington “recall how the Little Phatty came to life, the challenges that were faced when Dr. Moog fell ill, and how they were eventually overcome to create this one of a kind instrument.”

The Moog factory in Asheville, North Carolina will continue to build the last Little Phatty units from parts on hand. Moog Music is also offering a free percussion and legacy preset pack for Phatty owners available via download on its website.
