Death By Audio Apocalypse

Original FSB thread and schematic available here.
Rotary Switch is 2P5T and they are not always numbered.
I've called the 2 poles A & C.
When the switch is on "A-1" position on the other side is on "C-1" position... and so on.
Original circuits' schematics use Ge diodes but the Apocalypse's one doesn't. Need to test.

16/02/17 Layout Updated! There were a few mistakes in the first schematic:
Added 100n cap to Sw A-3, Reversed MPSA06 and connected TL072's pins 3 & 5.

Fuzzhugger Algal Bloom V2

From the Source 

The Algal Bloom is a harmonically rich, wide-range fuzz! From mellow to gritty overdrivey tones, to beautifully thick fuzz, to crunch, crust, and throaty fuzz roars! V2 adds an all-new Choke toggle that turns the Algal Bloom into a Harmful Algal Bloom, a raunchier mode that goes from dying to crusty, to crunchy, to whiplash! A new 3-way filter toggle lets you smooth clipping and highs for ultimate control.The Algal Bloom is known for its open tone and many chord-friendly settings, with fantastic definition and note-separation, even on high gain settings. The controls are uniquely interactive for incredible range. The pedal has a unique sound and circuit, but also expands on some classic tones that fuzz enthusiasts will love. A workhorse of a classicish, garagey, all-around capital F Fuzz. 


The Controls! 

Gain: Gain adjustment and clean-up! As you back it off, it cleans up your fuzz, also adding a hint of sputter and fizzle. Hard right is full-on!

Bloom (Fuzz): Expands and pushes your fuzz tone, adding gain, sustain, and definition. Hard right is maxed out...a unique, throaty, brash-yet-full tone! 12 o'clock is its "home setting," for thick fuzz tone!
 

Power: Controls the flow of power to the circuit, altering response, heft, and gain (slight scratch is normal, as circuit adjusts to voltage change)

.Level: Your master volume control.

 
• Choke / HAB Toggle: the V2's new Choke toggle, letting you dial in whiplash, crunch, crud, crust, dying, and dead. 

• Filter (3-way):
1) Middle: the unfiltered Algal Bloom you know.
2) Up: slightly smoothed highs, reducing clipping and fizz activity from the highs.
3) Down: smoothed and dampened.

WEM Pepbox

   This was requested in the forum. There is a photo of the Beatles where you can see this pedal, so it should be a fun build for us Beatles fans!


   Here's the Ge version first:



   
Then the Si version:



And finally the Si version with the tone control mod like the Ghost Effects kit:
