From the post
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.
