Parallel cleanish to heavily distorted signals, both of which stand alone quite well but get even better together. High and Low control the gain of their respective signal paths along with frequency response. Turn High up, get more gain and more treble, dig?
Very interactive with your volume and tone knobs. For real. I never trust that when I read it but it's true here.
Three-knobber has fixed 50/50 post-circuit blending where blend ratio is set with the High/Low knobs but you get changes in gain and frequency response at the same time. Five-knobber has fully adjustable blending (Balance) from all-High to all-Low and everything in between so you can have low gain High mixed 90/10 with highest-gain Low. Input is a pregain for precise tuning of just the sound you want.
Entirely discrete transistor/fet circuit. Top jacks, standard power, true bypass, etc.
I love everything about this concept. Anyone who's seen Ken's development has predicted great things out of his work, and so far he's going above and beyond to prove us all right!
