Got a request for this one for Fuzz Friday. Designed by Masaru Kubota it's based on Roger Mayer's Axis Fuzz with a fair bit of tweaks. Here's the schematic for reference.
I revamped Roger Mayer's Axis Fuzz and stuck on a phase stage to make the circuit sound like a tube amp. You probably notice the Dallas-Arbiter Fuzz Face biasing configuration. You can use a regular low-pass RC network, ala the ProCo Rat, to make the circuit sound like a "open" tube amp. This fuzz sounds ALOT like the "Modern Lead" amp model on my Zoom GM-200. You'll be surprised at how much this circuit sounds like a tube amp.
