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.
