Ross Phaser

This was a request.
The video is for reference only:

Crazy Tube Circuits Ziggy

 Info from their website:
"Ziggy is a low to medium gain overdrive that is designed to respond like a tube amp. Unlike most overdrives it does not feature a “mojo” opamp but cascaded discrete (MOSFET) gain stages that give ultra touch sensitivity so that you can control everything from your guitar’s volume knob and pick attack.
Gain knob acts as a voicing control adding more bass as you turn clockwise, choosing from jangly and sparkling clean to thick crunch of a tube rectified amp . Tone knob behaves as a presence control adding bite to your tone.
Inside the updated (white and gold version) we have included a two position gain switch. The higher gain setting has extra bite and sustain making perfect for lead sounds and is reminiscent of the now discontinued wine red Stardust"

I would like to thank Ziotasgiorgios for reverse-engineering his own pedal in our forum section and Nocentelli for drawing the schematic!
Thanks also to Hozy31 for verifying the layout!

Brunetti Mercuri Box

Here is a layout for the Brunetti Mercury (should fit in a 1590B size box).
Frank_NH has uploaded another verified, slightly modded version in the Forum section a while back.

This is the best video I could find (in Thai language):

Start biasing JFETs at 9V.

Madbean Sharkfin (Maestro FSH-1 Filter, Sample & Hold)

Here is Brian's modified version of the old Maestro FSH-1.
You could buy his PCB here and find all infos about this project here.

THAT Jam Compressor

Here is a DIY project similar to the Carl Martin Compressor Limiter.
There are 2 layouts: a large one that works at 9V and a smaller one where you need to decide a way to feed +/- 12V to the circuit (just a charge pump with regulators wouldn't work with this circuit).
You should read the original threads from FSB here and here before building this effect.
Good luck!
