PBJ EU - Greenface Labs

Proto Board w. Jacks for Eurorack

The PBJ EU. (Resistor added to light LED 3)

Everyone who develops or wants to develop Eurorack synth circuitry needs a PBJ.

Its simple design has evolved over the years to contain exactly the elements you need exactly in the places they should be. Once you’ve used the PBJ-EU, you’ll never go back to the old way of of developing circuitry that involved hooking up wires to a power supply and dangling jacks.

Because all the elements are already there, you don’t need to hook up a supply and jacks just to get started. Removing this barrier to actual development is, perhaps, one of the PBJ-EU’s finest benefits.

And if you ever want to transport your prototype, the PBJ-EU makes it an easy task as opposed to the nightmare of packing up a loose board and power supply.
