IN PROGRESS -- In this project I am designing pedal in which a user can plug in their guitar and, with the simple click of a button, change the sound signal of the guitar before it is output through an amplifier. The pedal will be designed with two sound profiles: an overdrive and a reverberation. The overdrive increases both the volume of the guitar and adds a dirty, static sound quality. It uses a MOSFET and a high value resistor to create the distortion and uses two potentiometers to control the volume and gain. The reverberation adds a clean sort of echo to the signal giving it a very haunting sound. It uses an op-amp chip and a reverberation module to create the distortion. It also uses two potentiometers except these control the amount of reverberation and the amount of dampening. So far I'm in the debug phase. I have rigged up the circuits on a breadboard and I will be connecting a guitar to ensure the circuit preforms as expected. Once I verify the design I will be placing an order for a PCB I designed through EasyEDA. I have also designed an enclosure using TinkerCad which I intend to 3D print once I have the board. Below are some images of the engineering process.
