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 is a three-person studio in Rotterdam dedicated to the repair and restoration of vintage synthesizers. We spend our days with soldering irons and oscilloscopes, coaxing life back into instruments that were built to last and mostly did, until they didn't.
Between us we cover decades of combined experience with analog and early digital circuitry, from the classics of Roland, Korg, Moog, and ARP to the odd, wonderful machines that never made it big. We treat every repair with the same care, whether it's a flagship polysynth or a broken drum machine with a devoted following.
Our workshop sits in the west of the city. You're welcome to visit — bring the instrument, bring the story behind it. We like hearing both.
What we don't know we research, and what we can't source we sometimes fabricate. Nothing gets written off before we've tried.
