Abstract: Guitar distortion has been an integral part of modern music since the 1960s. This was first done by overdriving the tube amplifier beyond its linear region, creating a harmonic distortion characteristic that is dominant in the 2nd harmonics, and changing to odd harmonic distortion as the output voltage swing is limited by the rail voltage. Guitar distortion pedals today seek to recreate the same sound effect of an overdriven tube amplifier with the use of nonlinear I-V characteristics of diodes. However, the odd harmonic tends to dominate in the harmonic distortion, different from tube amplifiers. This project aims to design a guitar distortion pedal that replicates the distortion characteristics of a tube amplifier - rich in 2nd harmonic distortion. The final product should be able to be used over a wide range of music genres, giving the user the ability to control the amount of distortion to taste and the frequency response of the pedal, also known as tone control.
