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 small workshop in Rotterdam where old synthesizers come back to life. We are three people — a former recording engineer, a self-taught circuit obsessive, and a classically trained pianist who fell in love with broken machines — and between us we have spent decades coaxing sound out of equipment the rest of the world gave up on.
We started Patchbay because we kept meeting the same problem: beloved instruments sitting silent in attics and studio corners, written off as unfixable. A Juno with a dead voice chip. A Prophet that drifts out of tune. A Moog that hums when it shouldn't. To us, none of these are lost causes. They are instruments with history in them, and they deserve careful hands, original parts where possible, and honest work.
Every synth that leaves our bench is played, tested, and listened to — because that is what it was made for.
