What do people build with it?

USE CASE 1

Order and hand-solder a DIY fuzz pedal to learn analog circuit building.

USE CASE 2

Build an octaver or clean boost pedal using the modular effect board design.

USE CASE 3

Learn how transistor and diode based guitar effect circuits work by building one yourself.

USE CASE 4

Swap different effect boards onto the shared base board without redesigning the whole pedal.

How do you get it running?

Difficulty · moderate Time to first run · 1day+

Requires ordering PCBs and components, then hand-soldering surface-mount parts before you have a working pedal.

Copy-paste prompts

Prompt 1
Walk me through ordering the PCB files from this repo at JLCPCB and sourcing the components from Tayda Electronics to build the fuzz pedal.
Prompt 2
Explain how the base board and effect board modular design works so I can build multiple pedals that share one enclosure.
Prompt 3
Help me understand the fuzz circuit schematic in this repo well enough to hand-solder it myself.
Prompt 4
I'm new to soldering surface-mount components. Guide me through assembling one of the 0805-size parts used in these pedal designs.
Prompt 5
Show me how to adapt the clean boost design in this repo to fit a different style of enclosure.
