P19361: Optoelectronic Guitar Pickup

Project Summary Project Information

Magnetic Guitar pickups have been used by guitarists seeking to add volume to their instruments since the 1920s. While magnetic pickups do the job of turning string vibration into an electrical signal that can be amplified, they are not perfect. Magnetic pickups are very susceptible to noise, particularly 60 cycle hum caused by alternating current power delivery and neon lights that are common in bars and other places that guitarists are likely to play. Magnets also exert a force that pulls on a guitar's strings, which can have a dampening effect. Neither of these issues are present in an optical pickup that uses infrared light to trace the vibration of a guitar's strings.

Previously, RIT students such as David Malanga have experimented with infrared guitar pickups. These designs served as a proof of concept, but were clunky, and got in the way of a guitarist's ability to play their instrument. The goal of this project is to improve on past RIT designs. The electronics used should be embedded within the guitar instead of outside. We will also experiment with sensor design, allowing improved playability and less sensitivity to being bumped during use, and research reflective options that don't have to be located on both sides of the strings like the current transmissive design. We will also experiment with effects via different DSP algorithms.
