Diamond Phase FM



  • Speed
    controls the speed/rate of the LFO wave that controls the effect
  • Env
    controls the sensitivity of the effect to the input signal.
  • Width
    controls the depth/amplitude of the modulation (the size of the range in which the effect sweeps).



Coming soon in Spring 2007! The Diamond Phase FM is a versatile new phaser with the ability to control the resonant frequency of the 4-stage opto-based all-pass filter with both playing dynamics and an LFO. Expression control is provided for LFO speed.

Diamond Phase FM Features:

  • 4-stage opto-based phaser
  • mixable envelope and LFO control of phaser resonant frequency
  • standard phaser operation by turning ENV control to minimum
  • 'auto-filter' operation by turning WIDTH control to minimum
  • envelope modulation of sweeping resonant frequency by adjusting both ENV and WIDTH
  • all analog circuitry
  • LED indication of resonant frequency (shows both LFO sweep and auto-filter range)
  • expression pedal control of LFO speed
  • true bypass operation
  • Vishay JFET, Burr-Brown audiophile opamps and Panasonic polypropylene capacitors
  • 9V battery operation, can also be powered by any standard pedal power supply with 9V negative tip
  • genuine Hammond cast aluminium 4.7 x 3.7 x 1.0 inch case
