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 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.

Patchbay is three people and one workshop in Rotterdam, and we spend our days bringing old synthesizers back to life. Most of what arrives at our bench is somewhere between thirty and fifty years old: a Juno with a dead voice chip, a Minimoog that drifts out of tune the moment the room warms up, a Polysix whose battery has quietly eaten its own circuit board. We know these instruments inside and out because we have had hundreds of them open on the table.

We started Patchbay because we kept meeting musicians who had been told their synth was not worth fixing. We disagree. These machines were built to be serviced, and with the right parts, enough patience, and a good set of schematics, almost any of them can be made to play again. When we hand an instrument back, we want it to sound the way it did the day it left the factory, or better.
