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 repairing vintage synthesizers and keeping electronic instruments alive. We work with analog and digital keyboards, drum machines, and modular systems, restoring worn circuits, replacing fragile components, and returning each machine to reliable musical use. Our small team combines careful technical work with genuine respect for the instruments that shaped decades of music. Whether an instrument needs a routine service, a difficult diagnosis, or a full restoration, we approach it with patience, clear communication, and attention to detail. We believe these machines are not just equipment; they are tools with history, character, and sound worth preserving. Based in Rotterdam, we serve musicians, collectors, and studios who want their gear maintained properly and played again. At Patchbay, every repair is treated as a collaboration between craft and music, ensuring that classic synthesizers continue to inspire new sounds for years to come.
