Moog Subsequent 25/37

The Subsequent 25 (25 keys) and Sub 37 (37 keys) are amazingly fat-sounding two-oscillator analog synths with a Duo mode that allow two-note operation (one oscillator going to each note). Add to this a sub-oscillator and the ability to overdrive the classic Moog ladder filter, and you get a beastly sound from this hand-crafted instrument.
