Wampler Sovereign

The Wampler Sovereign Distortion is a versatile beast of a distortion pedal that is unlike the rest of its ilk. The gain is rich and full of harmonic overtones, never sounding or feeling fake and stiff. Surprisingly shapeable and responsive, the non-traditional gain and EQ controls allow you to tune the pedal to suit any setup, and instead of just emphasizing a certain frequency range, they actually change the texture of the gain. With the right settings dialed up, it can nail the elusive sludgy deep sound loved by stoner metal guitarists, along with virtually every other shade of high-gain tone a player can imagine.

Here is a layout for the Rockett Flex Drive.

The layout has already been verified by Gavin (Hozy31).

This was an old request.

And a version with an added Notch Depth switch.

BYOC 27V Boost

Taken directly from BYOC.

Possibly the World's cleanest, most transparent boost. It utilizes the 7660S charge pump's ability to take a standard 9v power supply and output both +18v and -9v. The op-amp based boost circuit takes advantage of the whopping 27v differential to produce 20dB with an amazing amount of headroom. It doesn't matter if you're using active pickups - you will not get any clipping from this boost. Slam it with another boost, it still won't clip! The treble control allows you to cut/boost frequencies above 3k3Hz by 6dB.

To be honest, it's not as small neat as I would like it due to the three different power connections, but here she is. 

On the site it says it uses a 7660s for the charge pump, but the schematic shows a MAX1044, remember the two are interchangeable.
