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 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.
Patchbay is a three-person studio in Rotterdam, keeping vintage synthesizers in working hands. We repair the instruments that have picked up a crackle, lost a voice, drifted out of tune, or stopped making sound altogether.
We like the patient side of repair: tracing a fault, understanding an old circuit, and finding the right fix rather than the quickest workaround. Our aim is to make each instrument dependable without sanding away the character that made someone fall for it in the first place.
Some synths arrive with a clear problem. Others come with a story and a noise that only happens after twenty minutes. Either way, the work starts with listening—to the instrument and to the person who plays it.
We’re a small studio by choice. It keeps us close to the work, and to the musicians who trust us with something they want to keep making music with.
