Abstract/Summary
This product is a multi-effect pedal to be used with an electric guitar. This unit can distort and overdrive the weak signal from a guitar as well as add chorus, phaser, and compressor effects to the signal. Additionally, the user can choose different serial combinations of the effects, allowing full creativity and experimentation with a multitude of signal chain options. This product, having many different effects, saves space than if the effects were all individual devices. To interact with the product, there is a user interface with buttons, LEDs, and an OLED screen to allow the user to customize the pedal’s tonal characteristics and to make the product easier to use. For more customization of the pedal’s effects, including gain, effect speed, and volume, there are knobs on the device that can change these parameters in real time. All these features combined make the product a versatile, customizable, and easy to use device that is an essential part of any guitarist’s rig.
This project started as an idea over the summer of 2021 and initial development began during Fall Quarter 2021. Over the next two quarters, the schematic documents, PCB layout, and firmware was developed. At the end of Spring Quarter 2022, the device has been assembled but bring up is not yet complete. In this document, the entire system design is described and evaluated.
