Well, this BYOC Classic Fuzz kit is based off the silicone Fuzz Face, but with modern enhancements. It's also described as a very easy build, too.
I'm kind of tempted to order one of these... even though I already have 3 other fuzz pedals: A very early version of the Keeley Fuzz Head, a Fulltone Soul-Bender, and a Earthquaker Terminal.
