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.

6 s<$0.001208 tokensAPI

Patchbay is three people in a narrow workshop near the Maas in Rotterdam. Every day we open up instruments that were built before most of their current owners were born. Some arrive in flight cases and some come wrapped in old bath towels. Most have a story: a Juno that went quiet halfway through a gig, a Minimoog left in someone's attic for thirty years, or a modular system that a previous technician gave up on.

We started Patchbay because we kept seeing good synthesizers sent off as "unrepairable" when all they needed was patience, a schematic and a steady hand. We swap out dried capacitors, hunt for intermittent faults, recalibrate oscillators until they track properly again, and source or rebuild parts that stopped being made decades ago.

We don't try to make old machines sound new. Our job is to make them sound like themselves again, and to make sure they keep working for the next person who plays them.
