Hudson Electronics Sidecar
Lovetone Brown Source
There has been several schematics of this one over the years, each one having some bugs. But recentrly Lacesensor at FSB managed to do a proper trace and he posted thr corretions at FSB.

Death by Audio Absolute Destruction
A transatralntic trace by Enrico, AlexS and fuzzhead.
A big thanks goes to Enrico for letting us trace his pedal, all the images and the schematic.
The layout is tested and verified. There is some odd parts in there which can easily be subbed for other values. (221ohm to 220 ohm and 4,64k to 4,7k). MPSA05G transistors isn't that common but MPSA06 which is more widely avaiable works fine and is almost identical spec wise.
Also, Overload is linear, not log as in the first posted layout.

Fuzzlord Effects Void Master
A variation of the old one knob fuzz. Note that a few cap values and the potentiometer value is unknown.
First, power filter which suitable values should be 47uf or 100uf, I went with a 47uF in the layout.
Second. BC filter cap for Q2 is unknown but my guess is 220pF. This can be sockeded for brighter or darker tone.
Third. Potentiometer value is also unknown but a classic fuzz face/one knob value like 500k works fine.
Built this up a few weeks ago and it sounds fantastic and sounds just like the demos online. I used a BC108B for Q1 and a BC109C for Q2.
And another slightly smaller layout with the internal trimmers moved to the outside for external bias and fuzz controls, suggested by Jesuscrisp.
Glass Jaw
Another Acapulco Gold variation, this time with a bandaxall tonestack between the gain stages and with a buffered clean blend....

Colorsound Sustain Module 1 switch version
Here is a rare old and quite unique circuit that hasn't been traced before. With lots of help from AlexS and cobyjoe we managed to trace it and a have a working clone.
So what is it? Not to be confused with the Supa Sustain, this is a quite gnarly and fat fuzz with lots of output on tap. Some parts of the circuit resembles to a Fuzzrite (Q2 and Q3) with a feedback path that that has lots of odd things happening (Q4, Q1, D1 D2).
There is also a 2 switch version with an added switchable transistor stage but I haven't managed to trace it yet....

Catalinbread Dirty Little Secret V3
Slightly modified with the internal DIP switches moved to the outside and splitted into two DPDT switches. One is for gain and one is for the tonestack (Super Bass and Super Lead modes).
Schematic is avaiable HERE

Crowther Hot Cake 2008 version
Mode and XLF switches was internal DIP switches in original units but is moved to the outside per Aion Anomaly Vintage Distortion project. Schematic and circuit info is avaiable HERE.
