Mad Professor Amber Overdrive

Direct from the source:

One of the most sought after guitar tones is a combination of a great overdrive or fuzz pedal into overdriven tube amplifier. Amber Overdrive produces this sound even when running though a clean amplifier. It produces a very thick sound whether playing chords or single notes – fat and juicy with just a hint of fuzz.

Though highly saturated, this dynamic overdrive can be cleaned up with the volume control of your guitar. As with all Mad Professor pedals, it offers a wide range of dynamics and expressive touch sensitivity.

When you plug it into a clean amplifier, Amber Overdrive can give you the massive sound of a saturated amplifier running wide open. It can also be used as a slightly distorted boost to increase saturation on slightly overdriven amplifiers.

NOTICE: Amber Overdrive is a medium input impedance device that places a light load on your guitar pickups to produce a smoother tone. it will work best as the first pedal in the chain. if you run a buffered pedal ahead of Amber Overdrive you will get an increase in treble and upper midrange.

Catalinbread SFT II

Here is V.2 of Catalinbread SFT Overdrive.
You can find schematic and extra info on the original FSB's thread here.
09/08/16 Layout updated! Changed Sw6 to Sw4.

4ms Noise Swash

Another project by Commonsound/4ms.
You can find all info and schematic on their website here.
The original circuit uses a 1M Lin Pot with internal switch for the "Self Oscillation".
I've used a regular pot and an extra SPST switch but you can just use the original if you prefer.

4ms Phaseur Fleur

This was an old request.
Layout came out quite large.
You can find all info and schematic on Commonsound/4ms website here.

Valve Wizard U-Boat

This is a layout for TH Custom Effects' version of Valve Wizard's sub-octave pedal.
Here is the link to their website with more infos about this project.
