Boutique Amp & Pedal Electronics Repair
Tube amp repair, mods, pedalboard builds, and guitar electronics, done with lab-grade precision and road-tested practicality.
What I Do
Dr. Fuzz LLC is a Knoxville, TN–based shop focused exclusively on analog electronics. I repair, modify, and build amps, pedals, and pedalboards with an emphasis on reliability, noise control, and clean workmanship.
Why Dr. Fuzz
I’m Jordan Sangid, an analog electronics engineer with a PhD in electrical engineering from the University of Tennessee, Knoxville. Before the lab, I was the sound guy fixing cables in Knoxville bars. Today, I bring that same hands-on mindset to every repair, mod, and build.
This isn’t a volume shop. Every piece of gear is evaluated carefully, worked on methodically, and returned ready for real-world use.
How it Works
Start Your Project
Submit details about the gear and what you’re looking to do.Review & Follow-Up
I’ll follow up with questions as needed to provide an accurate estimate.Approval & Work
No work begins without approval. Diagnostics are credited toward approved work.
Built for Players, Not Just Benches
I work on gear that’s meant to be played. Vintage amps, noisy boards, half-working pedals, and rigs that need thoughtful fixes instead of guesswork.
Local drop-offs in Knoxville are preferred, but shipped-in work is welcome.
