Darkglass Duality Fuzz

 Happy Fuzz Friday! Here's a big one that hopefully makes up for my absence lately. Sounds great on bass and guitar. From Darkglass:

The Duality is a unique fuzz pedal that contains two discrete fuzz circuits—a gated saw-tooth wave and a raunchy high-gain sound—which can be mixed together to yield a vast selection of distinct sonic textures.

Gotten a few requests for this one and I finally got around to doing it. It's a bit of a hodge-podge–3 dual opamps, a hex inverter, and a JFET mu-amp array. Definitely not fitting this in a 1590B, but will fit nicely in a 1590BB with the pots board mounted. Info and schematic here.
