Where to get itAvailable from Soundtoyssoundtoys.com

PhaseMistress is a phaser plugin that recreates and expands upon classic hardware phasing circuits with unprecedented flexibility. It allows selection of any number of stages from 2 to 24 (including odd numbers rare in analog designs) and offers six modulation modes (LFO, Rhythm, Envelope, Random, Step, and ADSR) for dynamic frequency sweeping. PhaseMistress combines vintage-inspired presets faithfully modeled after hardware units like the Shin-Ei Uni-Vibe, MXR Phase 90, and Mutron Bi-Phase with exclusive modern designs and deep circuit customization.

04Resonance control with independent resonant peak tuning (Res Mod)
05Stereo L/R Offset and L/R Mode for wide, swirling effects

Things to Try

  • 01Set Frequency to 12 o'clock, Resonance to 9 o'clock, Mod to 12 o'clock, and select the 'STYLE TRYER' preset to audition different Style sounds
  • 02Set Mod knob to 11 o'clock and Rate to around 7 o'clock with Frequency at 12 o'clock for a standard phasing effect, then adjust Frequency to tune or bias the phasing
  • 03Crank Input or Output level to create pre or post-phaser saturation and distortion; increased harmonic content makes the phasing effect more pronounced
  • 04Use L/R Offset clockwise to increase right channel frequency relative to left, creating dramatic stereo width and swirling effects
