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 three-person studio in Rotterdam dedicated to the repair and restoration of vintage synthesizers. We spend our days with soldering irons and oscilloscopes, coaxing life back into instruments that were built to last and mostly did, until they didn't.
Between us we cover decades of combined experience with analog and early digital circuitry, from the classics of Roland, Korg, Moog, and ARP to the odd, wonderful machines that never made it big. We treat every repair with the same care, whether it's a flagship polysynth or a broken drum machine with a devoted following.
Our workshop sits in the west of the city. You're welcome to visit — bring the instrument, bring the story behind it. We like hearing both.
What we don't know we research, and what we can't source we sometimes fabricate. Nothing gets written off before we've tried.
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.
