Proving Ground
Build it. Hear it. Change it.
Proving Ground is a solderless workbench for guitar pedal circuits. Build a prototype, plug in your guitar and amp, and use the footswitch to compare your circuit with your bypassed sound. When you want to hear what a different component does, swap it on the breadboard and play the same riff again.
Available in Small, Medium, and Large.
See below for buying options.
Built for the bench
Audition your circuit. The true-bypass footswitch lets you switch between your prototype and your bypassed signal. The LED lights when the send and return loop is active.
Check your work. Dedicated test points give you access to raw 9V, filtered 9V, ground, send, and return.
Get wired up. Connect your guitar and amp to the built-in ¼-inch jacks. Use the included jumper wires to connect your prototype to power, ground, send, and return.
Includes 20 jumper wires. Requires a 9V DC center-negative power supply, sold separately.
