Hey, so here's a schematic of a few different circuit snippets hooked up together - the AMZ JFET buffer/splitter, Deadastronauts modified Phuncgnosis using the diode compression opamp to replace the TL072 originally used, a buffered blend, and an AMZ tone control at the end of the circuit. As of now its unverified - I won't get down to building this for atleast another week, so if anyone manages to try it out before then, or if there are any corrections/updates to be made to the schematic,do let me know :)

( envelope filter Phuncgnosis using diode compression opamp)
CORRECTION #1 - the pots, diode and caps near the GREEN LED (the only LED in the schematic) have to all be connected to ground - I've shown them as being connected to each other at one end but that's basically supposed to be part of the ground bus.
