Third Man Records Bumble Buzz

From the Source:

The Bumble Buzz Pedal, HAND MADE by Chris Young of Union Tube & Transistor (who built the pedal used for Jack White's guitar sounds on "Sixteen Saltines" and the vocals on "I'm Shakin'" off of 2012's Blunderbuss), is ready for buzzing around and stinging sounds. Designed by Third Man Creative Hive.

Input impedance: Zin @ 1KHz 30K / Output impedance: Zout @ 1KHz: 33K.

Essentially it's just a modified Kay F1 Fuzztone, which itself was just a simplified Univox Super Fuzz.

Frantone Lo-Tone Classic Fuzz

From the source:

At last... a classic fuzztone for bass!  This transistorized beauty uses germanium diodes for soft knee clipping and actually boosts the bottom to give you awesome sustain with rich creamy fuzztone.  Wonderful overtones and plenty of thump to boot.   

Earth Sound Research Graphic Fuzz

This is one of my favorite bizarre and unique fuzzes of all time. Gnarly, spacey, heavy, and broken. Nothing else sounds like it.

Induction on the forum a long time ago talked about how to make it so you can daisychain this beast, because you couldn't with the original. I found floating around in my files a schematic with the modification, so I figured why not just whip up a board.

Earthquaker Devices Black Ash

From the source:

Limited to 1500 units worldwide, Black Ash is a fuzz/overdrive that takes some cues from the vintage “three-knob Bender.” It uses a highly curated cache of rare and irreplaceable components including paper-in-oil capacitors and NOS half-watt carbon composition resistors from EQD President Jamie Stillman’s personal stash to light a fire under this classic fuzz/drive with an explosive-yet-detailed treble response, a sturdy midrange, and subterranean bass extension.

1. Fuzz: Adjusts the amount of gain. Counterclockwise for less fuzz, clockwise for more fuzz.
2. Top: Adjusts high frequencies between 2kHz - 10kHz and controls how “forward” the guitar sits in the mix. Counterclockwise for less top, clockwise for more top.
3. Level: Sets the output volume. Counterclockwise is quiet, clockwise is loud.
   
   

    It's essentially a modified silicon tonebender.

DOD 210 FET Preamp

Surprised this one hasn't been done. A nice small and quick build, and should have lots of boost on tap and fatten up your tone nicely. Could be a good platform to mod to taste. Seems to be on the rare side to boot. Only video I could find was a DIY build that has some mods, but you get the idea.

Earthquaker Devices Cloven Hoof V1

Sorry for such a long delay in publishing some new layouts, there's been a lot of changes going of for me which has taken up a lot of my time to sit and make some new layouts. Shortened version: became a doctor, had my first child with my wife, got a new job practicing, lots of home projects around the house, and COVID. Here's the first of many new ones from me coming at you. Figured I'd start with something familiar to all the fuzz lovers out there, as you can never have enough muffs.
 
From the Source:

The Cloven Hoof is an extension of Earthquaker Devices popular Hoof fuzz, only more… cloven. Earthquaker kept the clarity of the Hoof along with the wide range of dirt tones and redesigned everything around it. The Cloven Hoof delivers a grittier, more bass heavy tone with more crunch that can not be achieved with the standard Hoof. They did away with the germanium transistors and replaced them with 4 specially selected silicon transistors for higher gains, cleaner cleans and improved temperature stability. The fuzz control has four times the range of the regular Hoof, it will go from completely clean to an all out fuzz fury with more grind at the top end of the dial. The tone control has been refined to allow a more even sweep with enough mids to handle all the additional low end. The shift control still boosts or cuts the mids and there is still a TON of output on tap. The Cloven Hoof is the perfect solution for those of you who always wished the Hoof had more. Each Cloven Hoof is made by hand in the majestic mountain top village of Akron, Ohio.

Controls

Fuzz: Clockwise for heavy, counterclockwise for light.
Tone: Bass to the left, Treble to the right.
Level: Use this control to make the Cloven Hoof louder or quieter.
Shift: This adjusts the mid content, clockwise for scooped mids, counterclockwise for boosted.
