Abstract

Electric guitar players commonly use effect pedals to change the shape of their guitar’s signal, ultimately changing the sound of their guitar, in order to fit the style of the various types of music they are playing. Traditional guitar pedal setups include lots of individual pedals that are each independently powered, and each connected in series with a guitar cable in order to bring the effects from the guitar, to the amp, to the audience’s ears. This engineering capstone project sought a solution to the mess of individual guitar pedals, while maintaining classic analog sounds, by developing an integrated multi-effects pedalboard for the client of the project. Students on this team used open-source schematics to design signal-shaping effects to be integrated into this multi-effects unit. This honors capstone enhancement project took the scope of this project one step further, where a guitar effect circuit was designed completely from scratch. A tremolo effect was designed and added to the list of effects to be used in the multi-effects board. This tremolo effect features unique opto-coupling technology using standard, off-the-shelf components. The following presentation illustrates the design process of this effect circuit.
