The color pot subtly shifts the phasing frequency. All the way left, more bass passes through, and all the way right, less. The speed pot will take you from slow chugging evolving phasing to super fast tilt-o-wheel craziness!

For even more flexibility, the internal trim pot is a coarse frequency range selector. Set all the way left will allow the lower frequencies to be phasing, all the way right allows more high end frequencies to pass. This combination of the internal trim pot and the color main pot work in conjunction so you can dial in your specific range perfectly!

Runs off a 'standard' 9VDC neg tip regulated power supply (not included).
