The Wonk Machine is based on a schematic of the EQD Zap Machine, a negative ground adaptation of the vintage Zonk Machine.
It features an external bias control and an enclosure with classic inspired trade dress.
The Complete kit comes with everything you need, however if you just order the PCB or PCB and Case you can find almost everything else you need at StompBoxParts.com or LoveMySwitches.com in the USA or any other parts supplier worldwide.
See BOM for more information regarding part selection.
The case is a blue hammered 1590BB enclosure.
Complete kit first run limited to 20 units.
PCB and PCB/Case no limit.
Options:
PCB: PCB alone
PCB and Case: just the two things
Complete Kit: Everything you need to build the Wonk Machine, you just provide solder and wire.
