Pendletone Effects Proving Ground Pedal Prototyping Breadboard Workstation (Large)

Pendletone Effects Proving Ground Pedal Prototyping Workstation

Build the circuit. Proving Ground handles the rest.

The Pendletone Effects Proving Ground is a purpose-built breadboarding and prototyping platform for guitar-pedal builders.

It started with a simple problem: I was using a commercially available pedal breadboarding platform and liked the idea, but not everything about the execution—or the price. So I designed the Proving Ground around the way I actually prototype pedals at my own bench.

Instead of rebuilding the same supporting hardware every time you want to experiment with a new circuit, Proving Ground keeps the pedal infrastructure ready to go. You get permanent 1/4" input and output connections, true-bypass switching, power distribution and filtering, accessible test points, and dedicated signal connections surrounding three breadboarding areas.

That leaves you free to concentrate on the interesting part: the circuit.

Built for Pedal Development

Build your effect on the breadboards, connect it to the Proving Ground's SEND and RETURN points, and test it through an actual guitar-and-amplifier signal chain.

The platform provides accessible VCC and ground connections along with multiple test points, making it easier to measure voltages, troubleshoot a circuit, swap components, compare values, and experiment without rebuilding your basic test setup every time.

The circuit itself remains yours. Proving Ground doesn't impose a fixed gain stage, clipping arrangement, bias network, pull-down resistor, or other effect-specific topology on your design.

Whether you're breadboarding a boost, overdrive, distortion, fuzz, or something considerably stranger, you decide what goes in the circuit.

Who It's For

Proving Ground was designed specifically for guitar-pedal builders—from builders learning how classic circuits work to experienced designers who regularly prototype and modify effects.

The breadboarding system can also be used for other compatible breadboard-based electronic projects, but the permanent I/O, switching, power, and signal-routing infrastructure is purpose-built around pedal development.
