John Patton's demo:

EarthQuaker Devices Talons

Info about the original:
The Talons is an extremely versatile high gain overdrive that serves up the full range of gain from transparent boost to heavy saturation, and all points in between. Unlike all our other overdrives, the Talons was not designed to emulate any specific sound or era. The presence control gives you a wide range of top-end contour and the active 3 band EQ allows you to sculpt your tone to perfection. The Talons can be powered at the standard 9v for a warmer amp-like tone or at 18v for greater headroom, more volume and a brighter, stiffer grind.

Death By Audio Reverberation Machine

Info about the original:
The Reverberation Machine is a synthetic atmosphere creator. Use the effect on any instrument to add depth and simulate different environments. Experiment and combine a variety of settings to obtain the perfect ambiance for your sound.
The controls on this pedal are straightforward. Volume, Altitude, Reverb Blend and two distinct reverb flavors: Bright Sunshine and Dark Star. Altitude adjusts the gain structure of the reverb and the clean simultaneously creating exciting new reverberation soundscapes that span from subtle to wild.
Although the controls are extremely easy to use and intuitive, there is a vast array of sounds. Everything from simulations of vintage amp verb, playing in a cave, large concert halls, and space ships being sucked into wormholes.

UPDATE! Test values between 0 & 10K for R1 to improve Bright Sunshine side.

Sagan Delay

Another new gigantic layout for you!
This is a Chris Carter's project from Madbean's forum.
( http://www.madbeanpedals.com/forum/index.php?topic=20459.0 ).
He tried to create a PT2399-based delay that resembles the Roland Space Echo.

Twin Peaks "Tap Tempo" Tremolo

Another great project by David Rolo from Madbean's forum.

Thanks to Hozy31 for verifying it!
06/11/2015 Layout updated: inverted rotary switch pins.

Liquid Mercury "Tap Tempo" Phaser

I know this layout size breaks the basic rules of this blog but we don't have many Tap Tempo projects and
this pedal (together with the Twin Peaks Tap Tremolo) sounds incredible.
I think they both would be a great addition to the website's library.

Catalinbread Galileo MKII

Here is a layout for the Catalinbread Galileo MKII, the new, updated version of the well known Galileo.

Info about the original:
The Galileo is a custom-tuned Rangemaster booster combined with the pre-amp section of a Vox AC30 delivering the distinctive throaty mid-range and jangly crunch of Brian May.
The Galileo has three controls tuned to deliver the essence of the Brian May sound - GAIN, TONE, and VOLUME.
With guitar volume knob turned full up, you’ll get the soaring lead tones and tight but aggressive rhythm tones of Brian May.
Turn your guitar volume knob down slightly and you’ll be tying your mother down all night.
Turn your guitar down further and you’ll get an amazing jangly clean sound that isn’t really clean but is!
In a full band context, this pedal will cut through with just the right frequencies to fit perfectly in the mix.
