Back in the late 1960s, this modular beast powered some of the most groundbreaking electronic music experiments, with its ten discrete 901-series oscillators delivering raw, voltage-controlled tones that defined the Moog sound for generations.
Housed in two handcrafted solid walnut cabinets, it packs 36 hand-stuffed, hand-soldered modules including a 901 VCO, nine 901B oscillators driven by three 901A controllers, a pair of voltage-controlled filters (904A lowpass and 904B highpass) linked by a 904C coupler, three 902 VCAs, three 911 envelope generators, a 903A random signal generator, 914 fixed filter bank, 912 envelope follower, and that classic 905 spring reverb for lush tails. Patching happens via the 984 four-channel matrix mixer, 992 CV attenuators, 993 trigger panel, and four CP3 console panels with mixers, trunklines, switches, and filters—plus a 350W power supply for studio reliability. Monophonic by design, it's all about subtractive synthesis with patch cords routing signals through LFOs, mod matrix, and beyond.
Only 25 of these faithful recreations were ever made worldwide using original Moog docs and techniques, and owners cherish their warm, fat filter resonance and endless sound design potential, though the sheer size demands dedicated space.
