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, and we spend our days inside vintage synthesizers. We are repair technicians first: we open the cases, replace the leaking capacitors, re-tune the oscillators that have drifted out of pitch, and bring back the filters that went silent decades ago. Our bench is crowded with service manuals, spare chips, and a soldering station that has seen more Moog panels than we can count. We started the studio because we kept meeting musicians whose favourite instruments sat unused in cupboards, not because they were broken beyond saving but because nobody nearby knew how to fix them. We still believe most of these machines can be made to sing again, and we would rather spend an afternoon finding the one bad resistor than see another good synth end up in a skip.
