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 devoted to repairing vintage synthesizers and keeping electronic instruments alive. We work with analog and digital keyboards, drum machines, and modular systems, restoring worn circuits, replacing fragile components, and returning each machine to reliable musical use. Our small team combines careful technical work with genuine respect for the instruments that shaped decades of music. Whether an instrument needs a routine service, a difficult diagnosis, or a full restoration, we approach it with patience, clear communication, and attention to detail. We believe these machines are not just equipment; they are tools with history, character, and sound worth preserving. Based in Rotterdam, we serve musicians, collectors, and studios who want their gear maintained properly and played again. At Patchbay, every repair is treated as a collaboration between craft and music, ensuring that classic synthesizers continue to inspire new sounds for years to come.
Patchbay sits in a former warehouse on Rotterdam's northern edge, where the Maas meets the industrial harbour. Three of us work here—no more, no less—surrounded by oscilloscopes, desoldering stations, and the persistent hum of transformers. We repair vintage synthesizers. That is the whole business.
We are not a museum, and we are not a factory. Every Minimoog, ARP 2600, or Juno that crosses our bench receives the same stubborn attention: traced schematics, replaced capacitors, calibrated voltages, hours spent listening for the note that was never quite right. The machines arrive broken, silent, forgotten. They leave singing.
Rotterdam built its reputation on moving heavy things and keeping them moving. We apply the same pragmatism to circuits that predate us by forty years. If it made sound once, it can make sound again. That is the promise we keep, solder joint by solder joint.
