Mister-O

The Mr O recreates the original phase shifter released in the early 1970s (PS-1a) that was intended to replicate Leslie rotary speaker sound. Stays true to the original's six phase stages while packing it into a smaller, pedalboard-friendly footprint with enhanced flexibility for modern players.

Four controls provide extensive tone-shaping: Speed controls LFO (with waveform that adjusts at different settings to match the vintage original), Depth ranges from subtle shift to intense effects, Color manages feedback regeneration for adjustable "whoosh" character, and the 4/6 button toggles between six-stage (original) and four-stage configurations.

Running on ~70mA from 9V center-negative power, the Mr O delivers vintage phaser tones. True bypass switching. Recommended starting position: all knobs at 12 o'clock, switch in six-stage mode. Won Premier Guitar Premier Gear award for its authentic recreation of classic phase shifter sounds.
