About
Write the opening of the About us page for Patchbay, a three-person studio in Rotterdam that repairs vintage synthesizers. About 150 words.
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 dedicated to bringing vintage synthesizers back to life. We repair analog and digital instruments that shaped the sound of music, from classic drum machines and polyphonic synths to quirky, characterful machines that rarely leave a musician’s side. Our work combines technical knowledge with respect for each instrument’s history, because a synth is more than a circuit board: it carries the decisions, compromises, and personality of its original design.
We diagnose faults, restore unreliable voices, and carefully service aging components without erasing the character that made an instrument worth keeping. Whether a machine has been silent for years or simply needs a thoughtful tune-up, we treat every repair as a careful act of restoration.
Based in Rotterdam, Patchbay works with musicians, studios, collectors, and anyone who believes electronic instruments deserve another chapter. We restore them to sound as they should, preserving the details that make each one unique.
