The Zombie Chorus is one pedal that, for sure, you’ve never heard of it outside the DIY pedals community, but it’s definitely a classic that deserves a place on each player board. John Hollis originally designed this circuit and has been updated and improved through the years on many online forums.
Here you have our version ready to build with all the mods and corrections implemented, so you can make your analog dreams come true with this powerful brain eater Chorus/Vibrato!
This one is a circuit you can’t buy as a pedal. This not just makes it rare to own but also gives you tones non-DIY consumers will never have in their hands. Schematic is around in the DIY community for years, and it’s quite fun to mess with. So we simply added every mod we could research to it to give you all possible options this weird wobbling twangy chorus can give. Not only allowing you to use different modulation chips (usually the one that’s easier to source for you) by running jumpers. We also added two toggles to let you choose between chorus and vibrato: normal mode or Leslie type of sounds and its very own clone setting. We can’t wait to get feedback on how you guys like it.
Don’t get confused by C4‘s footprint on the pcb. It’s a 2.2nf (2n2) Film capacitor and not a 2.2uf electrolyte.
