MXR M-107 Phase 100



  • Intensity
    controls the depth/amplitude of the modulation (the size of the range in which the effect sweeps).
  • Speed
    controls the speed/rate of the LFO wave that controls the effect



This big brother of the Phase 90 offers a broader range of sounds in a larger unit. Along with the speed control there is a four-position rotary switch that selects four different intensities, defined as preset waveform patterns. Between the intensity and speed settings, you'll find quite a supply of excellent sounds tucked away in this orange casing.

The MXR Phase 100 represents the state-of-the-art in phase shifting. It is the first self-contained unit which offers programmable phase shifting through independently adjustable Speed and Intensity controlsK The four-position Intensity control allows for adjustment of sweep width, and also provides regeneration of the processed signal.

With ten stages of phasing, the applications of the Phase 100 are virtually limitless. Its low noise and high overload point allow you to use it with musical instruments (particularly keyboards), PA systems, and in the studio, without distortion. Such versatility, combined with an extreme long battery life (six months in normal use), makes the Phase 100 the ultimate in phase shifting
