According to Beavis, the kit is designed to make it easy to:

• Build a huge array of stompbox circuits including overdrives, distortions, fuzzes, filters, amplifiers, tremolos, noise generators, oscillators, and more.
• Learn about the different components and how they work to shape your guitar’s signal
• Modify stompbox designs to tailor your sound.
• Easily try out your circuits through a true-bypass breakout box

Kits are $249, which isn’t cheap, but looks like a fair deal. They are currently sold out.
