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 studio in Rotterdam where vintage synthesizers come back to life. We are three technicians, musicians and longtime collectors who have spent the last decade trading schematics, hunting spare parts, and learning the quirks of every oscillator and filter that has passed through our hands.
What started as helping friends keep their Junos and ARPs in tune has grown into a dedicated workshop in the north of the city. We repair, restore and service instruments from the sixties to the early nineties, from well-known classics to rare prototypes that barely left the factory.
We believe these machines are more than equipment. They carry histories, imperfections and sounds that cannot be replaced. Our job is to respect that character while making sure each instrument is reliable, playable, and ready for another lifetime of music.
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.
