About

Patchbay is a three-person studio in Rotterdam, dedicated to repairing vintage synthesizers and keeping them in use.
Old instruments have a way of becoming familiar: the feel of a key, the response of a filter, the particular sound a circuit makes when it’s working as it should. When something goes wrong, we take the time to understand both the fault and the instrument around it. We work carefully, preserving original parts wherever practical and making repairs with the long term in mind.
Our studio brings together a shared interest in electronics, sound and the machines that connect them. Whether a synthesizer has a stubborn key, a noisy output or has been silent for years, we’re interested in finding a way forward.
We work with musicians, collectors and anyone who wants to hear an old instrument come to life again. If you have a synth that needs attention, we’d be glad to hear about it.
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.
