Guitar Pedal Project Proposal

For my final project in Arduino for everyone, I would like to make a guitar pedal with programable effects. Initially, my goal is to make a distortion pedal. If/when that gets working, I can expand my range of effects to any level of complexity.

One reason I like this as a final project is because I am very interested in sound and the way computers process it. Prior to my interest in Engineering, I planned to make music my career, and was always deeply impressed by the monumental range of sounds that can be produced synthetically by computers, as well as the degree to which one can modify and shape existing sounds by running them through similar software. This project, and the resulting audio interface it creates, will give me a great deal of insight into how such programs work, the amount of detail that can be achieved in a particular effect if the person knows what they are looking to create, and also leave me with a reprogrammable model to work with and improve my skills moving forward.

Secondly, I will use a Teensy 3.2 to create this pedal, which is not an Arduino, but is Arduino compatible. This audio board is far more powerful than the Arduino, and is one of the most commonly used pieces of technology in home-made audio equipment, synths, etc. A Teensy-based guitar pedal  is an excellent introductory option for working with the Teensy.  

In addition to this, the circuitry of the guitar pedal design kit I am basing mine off of is quite complex. Although I am essentially replicating an open-source schematic to create the pedal itself, the intricacy of the design will provide ample room to learn, grow, and probably fry some components in the process.
