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 studio in Rotterdam devoted to keeping vintage synthesizers alive, playable, and full of character. We work on instruments that have spent decades in studios, bedrooms, and tour cases, and we believe each one deserves more than a quick fix. From drifting oscillators and noisy sliders to tired keybeds and mysterious faults, we take the time to listen, diagnose, and repair with care.
Our approach combines patient troubleshooting, period-correct components where possible, and a deep respect for the original sound. We do not believe in erasing an instrument’s history; we preserve the quirks that make it worth loving. Whether your synthesizer needs a full overhaul or a little help getting back on stage, you will always know who is working on it and why. Patchbay exists for the joy of switching on an old machine and hearing it come back to life.
