Overdrive Guitar Pedal

I have played guitar for over a decade and have am passionate about analog electronic guitar effects. I saw building my own overdrive pedal as a great opportunity to intersect my passion for guitars with my mechatronics experience. I have always wanted to have my own Ibanez Tube Screamer (a classic used by guitar legends such as Carlos Santana, Jerry Cantrell and Cliff Burton), so I built my own! ​

This pedal works by driving the "clean" guitar signal through a JRC4558D op-amp, which amplifies the signal with enough gain to give it the crunchy, distorted sound associated with hard rock guitarists. I replicated the original circuit design, sourced components and made all the electrical and mechanical connections. This project significantly improved my electrical signals debugging using an oscilloscope.
