This stompbox is based on the Brassmaster clone project from GeneralGuitarGadgets.
If you’re the plug-and-play type, you can simply order the PCB with all the components.
If you’re a bit more adventurous (like me), you can print and build everything at home.

The enclosure is designed for the 3-knob version and includes a dedicated compartment for a 9V battery.

The top shell is made of three additional plates that can be printed separately and glued together, or printed as a multi-color/multi-material piece. It’s compatible with any 3D printer.
Full wiring details can be found on the project page.
