I started my build series for Steel String Singer #002! :-) I'll be adding to this post as I make new videos

Fresh back from the screen printer, Steel String Singer #002!!! I invested and made 10x of these so I can sell it back at a discount to everyone who wants to build one too! I had the screen printer mask off "By Colgan" on 5 of them and the other 5 has "by Colgan" on it...

I was always curious about this pedal and the great reviews. If I could have SSS-esque tones from my Hot Rod Deluxe (for band practice), I'm in! I stumbled upon a layout on Guitar FX Layouts which was neat! I soon then stumbled upon PedalPCB's Six String Stinger and I...

Using LTSPICE, I modeled the Two-Rock John Mayer Signature to understand more about the circuit. LTSPICE makes it easy to change resistor/capacitor values and see a graph of the signal throughout the circuit. It was a bit of a learning curve as I've never had simulated...

A year and a half in the making! I'm finally done with this endeavor! It's been so much fun doing the research, learning a few new skills (AutoCAD, AutoDesk Inventor, Inkscape, GIMP, finger joints, etc.) I met a few friends along the way too which was nice.
