Don't Fret

Overview

The goal of this project is to create a device that takes a sound input, specifically from a guitar, and outputs a manipulated sound. The device will utilize a Raspberry Pi to take the input from an instrument and return an edited sound. The coding will most likely be done in C and allows for a unique effects from the standard reverb, fuzz, etc. effects as well as extensive capability to reprogram.
