Prometheus

SubDecay

  • $ 23500


The Prometheus is a voltage controlled 12dB filter which can be manipulated by playing dynamics or an internally generated signal.

The Prometheus is everything you've ever wanted in a filter pedal.
  • Loads of headroom
  • Reasonable size (measures about 3.7x4.7 inches)
  • Highpass, Bandpass, and Lowpass filtering with adjustable intensity (resonance)
  • Forward and reverse envelope following
  • Sample/Hold step filtering based on 3 different wave forms.
  • No special power supplies required. Operates with a single 9 volt battery or standard 9 volt adapter.

All that and it has some "hidden features" as well:
  • The LFO rate can be adjusted to run much faster than the the step rate. This can be used to create very interesting arpeggiation.
  • The Depth knob can push the filter cutoff frequency outside of the audio range. This can be useful to create a slow attack effect.
  • The step rate can be turned up high enough for smooth modulation. This can be used to create and autofilter effect, that can sound similar to a phaser or tremolo.
  • A fixed filter effect is possible by turning the depth knob down all the way, and using the
  • Frequency knob to set the filter cutoff.


  • The Prometheus is hand made in Dundee Oregon with high quality components.
  • Die cast aluminum enclosures for durability.
  • 3PDT switches for true bypass switching.
  • Runs for many hours on a single 9 volt battery, or can be powered by a 9VDC adapter.
  • Blue LED indicator.
  • Three-year limited warranty.


  • Powered by a 9 volt battery or 9VDC adaptor with a negative center 2.1mm barrel style plug.
  • Current draw is less than 15mA.
  • Input impedance: 1M
  • Output impedance: Less than 1K in HP and LP mode. About 5K in BP mode.
