Information
SubDecay
The Prometheus is a voltage controlled 12dB filter which can be manipulated by playing dynamics or an internally generated signal.
What's it do?
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.
Other features:
- The Prometheus is hand made in Newberg 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.
