About Us - Our Story

Founded in 2021 by Thomas Welladsen, Voltage Cable Co.® was born out of a deep love for guitar tone, design, and innovation. Our passion for boutique gear, reliability, and the music industry drives everything we do.

Handmade in Sydney, Australia, Voltage cables are built by experienced qualified technicians using only the finest components available and are backed by a genuine lifetime warranty.

As a family-owned and operated business, every cable passes through multiple hands before it reaches you. We strip, solder, seal, test, and package everything in-house at our small-batch operation in Windsor, NSW — just outside of Sydney.

Our mission is simple: to manufacture the best-sounding, most reliable cables on the market.

Voltage wasn’t built overnight—it was forged through local demand, years of experience playing guitar, building cables, and working on and modifying hand-wired amplifiers. All of these key ingredients, along with our experience working with touring artists, have ignited a no-compromise philosophy towards manufacturing the best products we can.

Before launching Voltage Cable Co.®, I (Tom) spent many years working in a small-town boutique guitar shop called River Music, surrounded by some of the best amplifiers like—Soldano, Bogner, Friedman, and the sought-after hand-wired vintage Marshalls. I’ve been playing guitar since I was 7, and getting a job in a store like River Music unapologetically kicked off a massive obsession with guitar tones, how those sounds were made, and what gear was used to get there.

At the shop, one of the most popular services we offered was modifying Marshall amps, gutting and rewiring Fender amps to be point-to-point, and adding custom circuits to other reputable amplifier brands.

During this time, I had the chance to work alongside Pete Reynolds—my old boss, the owner of the shop, and a valve amp genius with over 45 years of experience, modifying and repairing valve amps as well as designing and handcrafting his own brand—Reynolds Valveart. Pete’s deep understanding of sound, electrical engineering, and durability completely changed the way I looked at guitar products and influenced me massively with my own gear purchases and business decisions relating to everything Voltage.

Pete wasn’t just a mentor—he’s an old-school amplifier guru, a motorbike racer at heart (Triumph was the bike), and someone who believes that rock-solid reliability is the only way. Australian standards matter deeply to us. Today, Pete is the head technician at Voltage, and chances are, the cable you’re playing was made by Pete—hand-soldered, ISO-COAT® sealed, and meticulously tested to meet our tough Q/C standards.

Everything I learned working at River Music is now echoed through Voltage. From my first day to now, the story has come full circle—and we’re just getting started.

Working alongside Pete, I learned the true meaning of quality. I saw firsthand how every solder termination, every component choice, and every small detail could affect an amplifier’s tone and longevity. We spent countless hours diagnosing gear failures, fixing problems, and figuring out why some equipment stood the test of time while others failed.

One of the biggest issues we kept encountering—beyond amplifier failures—was bad cables.
