Tornado MK2

Explore a whirlwind of sound with a fully analog phaser


Estimated availability: June 2024


Tornado Phaser MK2 is a fully analog phaser that utilizes OTA AK317DC chips. It combines features from Ross™️ Phaser, EHX™️ Small Stone, and Blackout™️ Whetstone Phaser. Tornado Phaser lets you switch between two rates and range presets via a separate footswitch. Its cool features include vibrato mode, in-phase and out-of-phase phasing, ring mod, and chorus tones. Works great on clean and dirty (overdrive/distortion) guitar signals.


  • Effect Level - the amount of the modulated signal is mixed back with the input signal.
  • Resonance - feedback passed back to phaser stages; it adds some distortion to the signal.
  • Rate A/B - controls the modulation speed for each preset.
  • Range A/B toggle - switches between normal, fast, and slow rates, going from 40-second sweeps at the slowest to ring modulation and octave generation at the fastest.
  • Stages toggle - switches between 24, or 6 stages phaser; fewer stages means a more subtle effect.
  • Mode toggle - switches between 2 phasers (Phaser I - in-phase phasing, Phase O - out-of-phase) and vibrato modes.
  • Sweep toggle - switches between Wide and Shallow sweep modes for the LFO. It means how far modulated filters are going across the bandwidth.
  • LED brightness trimmers - placed on the PCB trimmers allow you to adjust the status LED brightness.
