Patchbay is three people and a bench in Rotterdam. We repair vintage synthesizers of all kinds, from a Moog that needs one capacitor to a modular system that hasn't been run in thirty years.

We started because older instruments deserve to keep working. The circuitry is simple, but the failures are personal: a dead pot in a favourite key, a CV rail that drifts, a ribbon controller that was saturated in smoke. We treat each case the way our own instruments would need to be treated.

A workshop is a good place for slow work and long conversations. We're always glad to open a system on the bench, find out what it actually needs, and explain why. If you have something unwell, send it over or come visit us in Rotterdam.

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.
