Mojo Hand FX Mr O-Phase Shifter 

The Mr O was created to reproduce the special and beloved sound of the original phase shifter pedal.

Released in the early 1970's intending to replicate the sound of a Leslie rotary speaker, the phase shifter turned into a widely popular effect that influenced the sound and role of the electric guitar ever since. After many hours of careful listening, playing, and tweaking, we finally arrived at a design that earned its colors and has the elusive magic of this historic pedal.

Mr O stays true to the original's six phase stages while packing much more inside of a smaller, pedalboard friendly footprint. Since the original had just three speed switches and no other adjustments, we gave the Mr O extra flexibility to satisfy the needs of a modern instrumentalist seeking the tones of this vintage classic.
