About Us

Guitar Amplifier PCBs specialize in developing, producing, and marketing affordable solutions to guitar amplifier circuits. By incorporating classic tube amplifier circuits into simple and convenient printed circuit board packages, we have been providing high quality circuit board solutions since 2008. Our customer base includes guitar amplifier enthusiasts from boutique amp shops to do-it-yourself amp modders all over the world.

Our first creation was a circuit board version of one channel of the legendary Marshall 18 Watt 1974x. It's a simplified version known as the LiteIIb. We call our circuit board version the "Baby Will". There's more to read about the Baby Will in its product page and you can learn more about the LiteIIb circuit over at 18Watt.com.

In the years since, we've launched and further developed our product portfolio to include another 18 Watt variant, the SuperLite II, and a 5 Watt single ended amp modeled after the Marshall Super Lead 50 Watt, the Plexi SE.

We developed a circuit board version of the famous Fender Tweed 5E3 and released it to the public domain through Wattkins Amp Forums. The PCB was incredibly popular and, thanks to it's versatility, it has been re-engineered by forum members to be a truly Universal PCB.

Sadly, the founder of Guitar Amplifier PCBs, Terry Stinger, was killed in a motorcycle accident in 2010, and his wife, Roxane kept the business alive for the next seven years. In 2017, Roxane asked Simon Higgs, a friend of Terry's who had been helping in the background, to take over running the business under Higgs Communications LLC.

Simon Higgs has previously worked for a number of musical instrument manufacturers including Gibson, 65 Amps, Zemaitis Guitars & Lipe Guitars, and is the founder and Executive Director of Wattkins Amp Forums, a 501c3 non-profit dedicated to guitar amp building.

So, thanks for stopping by. Make yourself at home and feel free to browse around. We've created all kinds of neat stuff.
