PCB Sellers for Audio DIY Projects

Stompbox PCB sellers

PedalPCB (Albany, Georgia)
The most accurate reproductions of original circuits you’ll find; no changes in component values, no mods. Over 600 projects available. This should be your first stop, especially for dirt circuits.
MadBean Pedals (Hendersonville, Tennessee)
(Circuits are often tweaked beyond the original. Brian incorporates the best mods so you don’t have to glom them on yourself. Limited edition projects are not stocked indefinitely, so buy those PCBs you’re interested in while you can.)

I’ve mostly excluded companies specializing in fully-built pedals, kits, and synth projects.

Lectric-FX (Marble Falls, Texas)
Lectric has some projects you can’t get anywhere else. Want to build an EHX Small Stone? A DOD Meat Box? This is the only shop that stocks ’em.
AION (Winsor Heights, Iowa)
Primarily a kit company, but plenty of DIY PCBs are available. Their documentation is highly regarded.
Tonepad (New Orleans, Louisiana)
An early haven for self-etching files, this is where my obsession began. They’re still around after more than 20 years!
