Designed by Bob Moog in 1999, this analog phaser traces its roots straight back to the modular synths of the 1970s, delivering swirling, psychedelic sweeps that feel alive and organic on everything from guitars to synth patches.
It's a fully analog 6/12-stage voltage-controlled phaser paired with a wide-range LFO spanning 0.01Hz to 250Hz via Rate knob and Lo/Hi switch, where you can shape the modulation with Wave, Depth, and Tap Tempo controls. Sweep glides over six octaves, Resonance sharpens those peaks from subtle to screaming, and the 6/12 Stages toggle adds three or six frequency dips for everything from gentle motion to intense vortex effects. Drive handles input gain with optional overdrive warmth, while Output balances the wet signal; it takes a mono 1/8" input but spits out main and aux jacks for stereo imaging. Housed in a rugged black chassis with wooden sidecheeks and those satisfying Minimoog-style knobs, it invites CV/Gate patching via dedicated expression inputs for Sweep, Resonance, Depth, Rate, and even a separate Sweep In to split the stages independently.
Players have long cherished its hands-on responsiveness and that unmistakable Moog depth, turning static sounds into breathing landscapes—though some note its hunger for rack space in tight setups. A true vintage gem for anyone chasing authentic analog movement.
