From the post
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!
