What Happens When a Pro Pedal Builder Builds a DIY Pedal Kit? If you ever wanted to know what a professional pedal builder would do differently with a DIY pedal kit compared to most others, or if you're into DIY pedal building yourself, you’ll love this. I’ll be using the StewMac Screamer kit and showing you just what I personally do if I buy a DIY “build your own pedal” type kit, how I approach the circuit, and just why I rarely, if ever, follow the exact instructions and instead I completely change it into something personalized, unique, and inspiring to play.
First, I’m going to get the schematic from the kit documents and decide just what I want to do differently. I’ll use a breadboard for circuit experimentation to do this.
_____________________________________________________________________
🔥My newest course, *“Complete Beginners Guide: How to design your own guitar pedal circuits”* will detail exactly how to do this, even if you have *zero experience with electronics* - I’ll teach you everything in easy to understand language, no math involved, and we’ll do it with a guitar in hand.

We’ll discuss how to recognize circuit blocks in order to do these types of changes. We'll look at examples like the Tube Screamer, Boss SD-1, LovePedal Eternity, and Earthquaker Devices Plumes for examples of 4 pedals with similar topologies that all sound completely different. We’ll also compare not only the circuitry of these pedals but also play them side by side for a sound comparison.
Then, it’s time to make the magic happen! I’ll start building the pedal and get to the end, but guess what? IT DOESN’T WORK! 🤦♂️That’s ok though - it’s a great chance to walk through troubleshooting the pedal and get it working.
Lastly, the play test! How does it sound compared to the breadboarded Prototype version?
