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.
Patchbay was born from a simple frustration in Rotterdam: the belief that vintage synthesizers should be heard, not locked away in climate-controlled collections. Founded by three engineers and musicians who share an obsession with the raw, unpredictable character of analog gear, we operate out of a small studio where the smell of soldering iron and ozone is as common as coffee. We don’t just fix broken circuits; we restore the soul of these machines. Whether it’s a temperamental Moog, a glitchy Roland, or a rare obscure European find, we treat every patch cord and potentiometer with reverence and precision. Our trio combines decades of electronic music production experience with meticulous hardware restoration skills, ensuring that every repair honors the original design while making the instrument reliable for modern stage use. We believe that the quirks of vintage technology are features, not bugs. Our goal is to bridge the gap between historical preservation and contemporary creativity, giving these legendary instruments a second life in today’s soundscapes. Join us in keeping the analog signal chain alive.
