Red Witch Fuzz God II

12/12/2015 Layout updated!
Swapped 2n2 and 56p caps in the Treble Switch as suggested by Nocentelli.
Info from the original:

Fuzz God II - the insane silicon brother of Germanium Fuzz God.
It's wilder, it's crazier, it's the loose cannon sonic brother that you wouldn't introduce to your girlfriend, cause you know he'd try his luck with her.
Fuzz God II allows you to create fuzzyness of epic proportions (think red seas parting, burning bushes, pillars of salt etc).
From your classic fuzz tones of the sustaining, soulful, singing kind through to those of utter chaos - encompassing suboctave madness, parasitic sustain and out of control fax machine dial lunacy.
More useable. More interactive. More versatile

Thanks to Jondog for the schematic.

12K has been reported as the best value for R1.

Keeley PSI

Info about the original:
We set out to take a classic design with lots of history  and make it obviously something new.
We took the op-amp version of old PI and inverted one of the stages, brought out the midrange, tightened the bass, and most importantly, added a Germanium transistor output!
Yes, this is a opamp-transistor hybrid.  Don’t be miffed by op-amps in your pie folks, the germanium touch at the end makes everyone smile around the shop here.

Keeley Oxblood

Info about the original:
The Keeley Oxblood Overdrive is our response to everyone kloning pedals.
We wanted to build a new circuit that let players blend from perfectly clean to amp-crushing roar.
We wanted that impossibly huge and focused midrange that makes any guitar… Strat, Paul, Tele, sound incredible.  We knew we could do it our way and offer you more tone.
So we designed this pedal over the course of a few days to outdo the klones.

With the Keeley Oxblood Overdrive you roll off the Drive Control down and get a perfectly clean sound, you can dial in any amount of distortion and volume to stomp an amp into pure tonal nirvana.  The Keeley Oxblood Overdrive offers you two ways to clip and saturate your signal with overtones by selecting carefully chosen diodes.  Magical and Mythical, Monstrous and Most Satisfying they are indeed.

 

EarthQuaker Devices Bit Commander

Hi guys! Alex here and I'm very excited to join the tagboardeffects squad. Thanks to Mark and Miro for the opportunity, and thanks to Travis, Zach and Javi for joining along.
My first contribution to the main site is a great guitar synthesizer from EarthQuaker Devices.
I would like to thank Njokki for reverse-engineering his original pedal.

Info about the original:
The Bit Commander is a monophonic analog guitar synthesizer with four octaves of vintage square wave synth tones. Its no-nonsense interface makes it easy to add or subtract octaves to create a wide variety of sounds without having to dial in envelopes or oscillators. Ripping sub-octave thump, pulsing octave down, a lightly squared base tone and a swelling transformer based octave up all join together to make a single guitar sound like an army of olde tyme synths.

 

Aria Super Fuzz Sustainer

Pawel from turretboard.knucklehead.dk (aka sinner from FSB) has very kindly offered for us to post some of his layouts which no longer fit with the theme of his website, and so we're starting off with the Aria Super Fuzz Sustainer.

I can't find much in the way of marketing info so don't know what Aria had to say about it (any info gratefully received) but here is a short youtube video I found:

I'm sure everyone will join me in saying thanks to Pawel.
