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 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.
Patchbay is a small workshop in the heart of Rotterdam, where three people spend their days elbow-deep in the guts of vintage synthesizers. We fix the machines that made the sounds you grew up with—the ones that shaped entire genres and then got left in basements when the tech moved on. But we're not a museum. Our benches are covered in solder, schematics, and the occasional broken key that's been there for two weeks longer than we'd like to admit.
We started this studio because we got tired of seeing classic gear being stripped for parts, or worse, turned into Instagram decor. These instruments deserve better. They were built to make noise, and we want to keep them doing exactly that.
Between the three of us, we've fixed everything from a 1960s Buchla to a beat-up Juno that fell down a flight of stairs. If you've got a synth that's gone quiet, bring it in. We'll bring it back.
