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 workshop in Rotterdam where vintage synthesizers come back to life. Whatever lands on our bench — a battered Minimoog, a Juno with dead keys, an ARP silent since the eighties — gets the same treatment: careful diagnosis, honest advice, and repairs done right.
We started Patchbay because we believe a good synthesizer shouldn't die of old age. These machines are more than circuits and sliders — they're the sound of records you grew up with, and the reason some of us got into music in the first place. Every one we fix goes back out into the world ready to make more.
Between us we handle everything from recapping and calibration to keybed work and the hunt for parts nobody has made in decades. It's slow, meticulous work, and we like it that way. If something in your collection hums, crackles, or refuses to turn on, bring it in — we'll see what we can do.
