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. We work on the instruments that have shaped decades of music, from well-loved studio staples to curious machines that have spent years in storage.

Old synthesizers develop problems in their own ways. A key stops responding, a filter drifts, a power supply gives out. We take the time to trace the fault, understand the instrument and make a repair that respects how it was built. Wherever possible, we preserve original components; when a part needs replacing, we choose with care.

We know these instruments are more than collections of circuits. They carry sounds, habits and memories, and each one has a story before it reaches our bench. Whether you rely on yours every day or are hoping to hear it again after a long silence, our aim is to help you get back to making music.

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.
