Winter 2014 For my project I am building an electric guitar analog effects pedal. The pedal is called the "Tube Screamer" and is an overdrive effect, which clips an amplified signal.
Why build a guitar pedal? I want to understand what makes overdrive sound good. Oftentimes, when people speak of "distortion", they are talking about noise that is unwanted, but with guitars, there is a good distortion, which make the guitar signal sound good. As I built the pedal, I analyzed it with an oscilloscope, as well as did research, to better understand what makes it sound qualitatively good to human ears.

An electric guitar works by converting sound into an alternating current, using pickups. A pickup is a magnet with wire densely coiled around it. It creates a magnetic field around the guitar string, so that when the string vibrates, there is a change in the magnetic field, and a voltage is created in the coiled wires.
