About Sharkbomb Audio

Background

My name is Evan Demsey. I'm an electrical engineering student at the University of Virginia. My path to choosing electrical engineering is quite unique: audio. In 2020, I learned about the mythical "Klon Centaur" guitar pedal, which drove me to learn the basics of pedal building and audio design. I started making pedals for myself, to mimic the sound of some of my favorite guitarists. I began selling them to friends and taking repair jobs from friends and local used music stores, working under the name Sharkbomb Audio. Since then I've designed and built 20+ guitar pedals and 6 guitar amplifiers for amateur and professional musicians, and repaired more than 50 pieces of gear for three music stores around Washington, DC.

In 2023 I reached out to Paul Smith, the founder and CEO of PRS Guitars. He selected me to design, build and repair equipment for his studio. I still work with Paul closely in my free time, helping translate his audio needs into physical equipment. Since then I designed a 4-layer BGA carrier board as an intern at the U.S. Army Research Laboratory, and spent summer 2026 on the production line at EarthQuaker Devices.

At UVA, I enjoy teaching other students about fundamental electrical engineering topics as a teaching assistant for 225 students across 4 periods of signals and systems, applied circuits, and digital logic design. Outside of engineering, my love for music continues! I'm a member of UVA's Cavalier Marching Band and Athletic Band. I also founded the Birding at UVA Club, which now has 350 members and has sparked a partnership with the National Audubon Society, and of course I still love spending time designing and building audio equipment. If any of this piques your interest, please reach out. I'd love to hear from you!

What I take on

Custom builds
Pedals, amplifiers and studio equipment designed around your performance goals, then simulated, prototyped and measured on the bench.
Modifications
Changes to gear you already own that improve its tone or performance, informed by reverse-engineering the original circuit.
Repair
Diagnosis and repair of commercial audio equipment. 50+ repairs completed for three music stores around Washington, DC.
