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 devoted to repairing vintage synthesizers. We work with instruments that have been played, carried, opened up, and passed from one owner to the next. Each arrives with its own history and its own set of quirks, so we begin by listening carefully and tracing the problem before reaching for a fix.
Our work ranges from straightforward maintenance to deeper electronic repairs. We clean, test, diagnose, and restore with the aim of making a synthesizer reliable again while respecting the design that gives it its voice. When a repair calls for a replacement part, we look for a solution that fits the instrument rather than treating it as disposable.
Patchbay is run by three people who share a curiosity about how these machines work and a respect for the sounds they make. We believe a well-cared-for synthesizer has plenty more music in it, and we’re here to help it find its way back into someone’s hands.
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.
