This project experiments with C language to discover and design a programmable guitar amplifier effects micro controller computer section of a tube and solid state designed guitar amp. This a collaboration electronics project with my son. The goal of this project is to use Arduino hardware with C language programming to manipulate the guitar signal by various effects of phaser, flanger, reverb, digital delay and echo, and tremelo. Also, the signals of two microphones, two guitars, and one mp3 device will be inputted into and passed through two 3-band programmable equalizers. All of the processed signals will pass through and be amplified by a clean master volume controlled power amp. The digital effects will be toggled by means of a floor panel controlled by digital foot switch controller communication with the Arduino hardware via a digital cable. Also, the preamp signal can be alternatively connected to a separate power amp.
