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 repair studio in Rotterdam dedicated to vintage synthesizers. We work on analog circuits, replace failing capacitors and resistors, calibrate unstable oscillators, and restore instruments that have been silent for years. Our bench sees early Japanese mono synths, European string machines, American polys, and large modular systems. We treat each repair as a specific problem rather than a routine job, because these machines were built differently and fail differently. The studio grew out of our own need for careful, local repairs. Over time, musicians, collectors, and producers across the Netherlands started bringing us gear they could not trust elsewhere. We open every case with the same approach: diagnose the fault properly, use appropriate parts, and test the result thoroughly. We do not apply quick fixes or ignore underlying issues. Whether your synthesizer suffers from tuning drift, dead voices, noisy outputs, or an unknown electrical fault, we are in Rotterdam to find the cause and return it to reliable working condition.
