green ringer/shocktave pedal recommendations

[peterg]

I'm building a green ringer/shocktave combo pedal and am looking for recomendations. I've breadboarded it using section 1 (don't know the proper name) of the shocktave circuit for both octave up parts and octave down parts
1. How do I get rid of the static from the shocktave? It is present in the decay on all notes. Seems to be occurring in the second part of the circuit.
2.  What would be the best  first section 1 to use for both octaave up and octave down parts?
3. Considering a switched outjack for the octave down circuit. The idea is to direct both effects to a single jack unless there is a cable running to a bass amp plugged in the second out jack.  The switch would cancel running the octave down sircuit to the first jack. With 2 cables the octave down goes to a bass amp and the octave up goes to a guitar amp. Any suggestions on wiring using a typical 3pdt foot switch and an LED?

Hi Peter.
I've built two shocktaves (one is the "derringer" layout, the other on a etched pcb).
A couple of things I've noticed for getting good results:
Matched transistors. I've read that the important ones to match are Q5-Q6. I try to keep them all pretty close, but make sure that those are almost identical (it's hard to get perfect matches, even silicon reacts to temperature a little bit.)

Shocktave likes a smooth, strong signal going into it, without a lot of high frequencies.
I have been experimenting, and found that a preamp with treble rolled off and bass boosted let the signal decay almost normally. And taking was greatly improved. I would think about doing a BMP tone stack on the input for my next one....

There is a guy named cortexturizer who did one built up with a Super Fuzz, he ran the shocktave into the super fuzz. His sounds super.
I can't really answer your other questions, as I've not had experience with pairing this circuit with anything other than a preamp.
