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 three-person studio in Rotterdam, dedicated to repairing vintage synthesizers and keeping them in use.
Old instruments have a way of becoming familiar: the feel of a key, the response of a filter, the particular sound a circuit makes when it’s working as it should. When something goes wrong, we take the time to understand both the fault and the instrument around it. We work carefully, preserving original parts wherever practical and making repairs with the long term in mind.
Our studio brings together a shared interest in electronics, sound and the machines that connect them. Whether a synthesizer has a stubborn key, a noisy output or has been silent for years, we’re interested in finding a way forward.
We work with musicians, collectors and anyone who wants to hear an old instrument come to life again. If you have a synth that needs attention, we’d be glad to hear about it.
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.
