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 bringing vintage synthesizers back to life. We started with a shared obsession for the circuits, keyboards, and sonic quirks of the instruments that shaped electronic music, and we turned that obsession into a careful, hands-on repair practice. Every synth that comes through our door is treated as its own project—diagnosed by ear, opened with care, and restored using a mix of original components and thoughtful modern solutions where needed. We work with collectors, studios, and musicians who value the character of older gear and want it to keep sounding its best. Based in Rotterdam, we combine technical precision with a deep respect for the history inside every chassis. At Patchbay, repairing isn’t just about getting a machine working again; it’s about preserving the voice of an instrument and keeping it ready for the next recording, performance, or moment of inspiration.
