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 the industrial heart of Rotterdam, Patchbay is a three-person workshop dedicated to the survival and revival of vintage synthesizers. We started with a simple conviction: these instruments are not museum relics meant to gather dust behind glass, but living, breathing tools of expression built to make noise. Across our three workbenches, we combine decades of obsessive circuit-tracing, soldering, and component-level diagnostics. Whether coaxing a temperamental Japanese polysynth back into tune, rebuilding a tired power supply, or hunting down elusive, out-of-production chips, we treat every machine with meticulous patience and deep technical reverence. Rotterdam is a city shaped by honest craft, and we bring that same pragmatic devotion to every solder joint and calibration trim. At Patchbay, we don't just repair obsolete electronics—we preserve the warmth, grit, and soul of analog sound for the musicians who still rely on it.
