What do you do with 40 knobs, 74 switches, and double the headroom of the Sub 37 Tribute? You craft some of the thickest, grittiest, richest sounds an analog synthesizer has to offer. Able to operate in both monophonic and paraphonic (two-note) modes, the Moog Subsequent 37 retains the architecture that made the original an icon with tweaked features like a redesigned Ladder filter gain stage and re-tuned Multidrive circuit for an expanded palette of Moog tone.
