The Moog Sub 37 Tribute Edition is an expanded 37-key version of the Moog Sub Phatty analog synthesizer. This is one of the first products from Moog in decades to offer polyphony with its 2-note paraphonic Duo Mode. Featuring classic analog tweak-ability with its 40 knobs and 74 switches as well as modern reliability and 256 presets of memory, the Moog Sub 37 is a veritable electronic painter's palette for creating new sounds and music.
