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 began in a small, cluttered workshop in Rotterdam, where solder smoke and old capacitors seem to belong together. We are a three-person studio, which means every synthesizer that comes through our door is handled by one of the same people who started the project. No call center, no hand-off to strangers. We repair vintage synthesizers: the dusty analog beasts, the rare oddities, the ones with missing knobs and mysterious tuning drift. Our work is part electronics, part archaeology, part stubborn love. We listen to the hum before we open the case, and we believe most vintage synths are not dead, just waiting for someone to pay attention. In a city known for moving quickly, we prefer taking our time. Patchbay exists to keep old voices alive, one oscillator, filter, and power supply at a time. If you have a synth that sings, whispers, or hums through the decades, we would be glad to meet it.
