Distortion Control

This project explores the design of the pre-amp stage of a typical electric guitar amplifier. It requires knowledge of the operation of operational amplifier circuits and RC circuits. A volume control, bass/treble equalizer, and variable distortion were all implemented in this pre-amp design using analog filters and op-amps. The design was formed after research on the Internet of how to design an analog equalizer and distortion circuitry. These features are very common and useful for amplifying guitars. The circuit was first tested using a Pspice simulation. Next, a function generator, DC power supply and oscilloscope were used to test it on a breadboard. After successful testing, a printed circuit board layout was designed and ordered online. The components were then soldered onto the printed circuit board and placed in an enclosure for the final product. This project was a learning experience in design of these pre-amp circuits, as well as the fabrication and manufacturing process that is implemented to produce a final product
