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 with a very specific obsession: bringing vintage synthesizers back to life. We are three technicians and musicians who spend our days surrounded by circuit boards, calibration tapes, and the smell of solder, coaxing sound out of machines that have been silent for years. From wobbly oscillators and dead keys to crackling faders and drifting filters, we diagnose, repair, and restore analog instruments with the patience they deserve. Our workshop is stocked with rare spare parts, original service manuals, and a deep archive of hard-won knowledge about classics from Moog, Roland, Sequential, Korg, and ARP. We love these instruments not as museum pieces, but as living tools that still have music in them. Every synthesizer that leaves our bench is tested, played, and calibrated so it feels reliable enough for the stage, the studio, or the late-night jam that inspired it in the first place.
