About Dr. Fuzz

I’m Jordan Sangid — an analog electronics engineer (PhD EE) who builds, restores, and modifies tube amps, pedals, and guitar electronics.

Before the lab coat and oscilloscopes, I was the sound guy and bartender at Knoxville’s Longbranch Saloon. When the bar owner handed me a $10 Radio Shack soldering iron to fix a pile of busted mic cables, everything changed.

That spark led from bar stages to engineering labs, from punk shows to circuit design. Today, under the Dr. Fuzz name, I blend that road-worn grit with lab-grade precision — every repair, mod, and build is methodical, measured, and clean.

Specialties:
Fender Black/Brown/Silver • Marshall JMP & JCM-800 • Post-PI Master Volumes • Lead-dress cleanup • Noise & oscillation hunting • Vintage restoration • Pedal mods • Guitar electronics

1961 Fender Bassman 6G6, fully restored.
When this one came in, it had lived a long life, and somewhere along the way a friend of the owner decided to make “improvements” to one of the greatest amp circuits ever made.

After weeks of care

The past few weeks I’ve had a blast sharing music + electronics with kids in the community. From jamming on the Korg at the YWCA afterschool program 🎶⚡️ to setting up sounds and circuits at my kids’ school STEM night, the curiosity was e

STEM + Music = Magic

Getting ready for some upcoming STEM events. I’ve been putting together posters and planning out the booth. My setup is simple: a synthesizer and a theremin, and I just let the kids go nuts.

It’s amazing watching th

This is my first time going out to STEM fairs to try and spark curiosity about engineering. I made these “Future Electrical Engineer” stickers to hand out to kids, and I’m pretty pumped about it all.
