About

Write the opening of the About us page for Patchbay, a three-person studio in Rotterdam that repairs vintage synthesizers. About 150 words.

Patchbay is a compact, three-person workshop rooted in the dynamic streets of Rotterdam, born from a shared reverence for analog sound. Our team shares an unwavering dedication to vintage synthesizers, viewing each oscillator, filter, and routing cable as a vital piece of sonic history waiting to be restored. Whether diagnosing a failing voltage regulator or carefully retrofitting obsolete components, we take immense pride in bringing classic instruments back to their full potential. In our studio, repairing isn't just a technical service—it is a shared passion among friends who believe the past deserves to keep playing. We meticulously diagnose and revive legacy synths, ensuring the iconic sounds of yesterday continue shaping today’s electronic music. Bring us your dented, broken machines, and let us help you reconnect them with the rich, unmistakable sounds they were always meant to make. Every patch, every knob, every fleeting tone depends on the work we do here.

Tucked away in Rotterdam, Patchbay is a three-person repair studio dedicated to the preservation and revival of vintage synthesizers. We believe that classic instruments are living machines rather than museum relics—tools built to inspire, create, and be played loud. Between the three of us, we combine decades of experience in electronics engineering, sound design, and meticulous craftsmanship. Whether tracking down elusive voice chips for an eighties polyphonic giant, rebuilding power supplies, or recalibrating the drift on a cantankerous monophonic circuit from the seventies, we treat every piece of gear with obsessive attention to detail. Our workbench is built on a deep respect for historical engineering and a refusal to cut corners. For musicians, producers, and collectors across the Netherlands and beyond, Patchbay is where forgotten circuits find their current again, keeping the tactile soul of analog synthesis alive and resonant.
