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 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.

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.
