Patchbay is a three-person studio in Rotterdam dedicated to the repair and restoration of vintage synthesizers. We are engineers, musicians, and collectors who believe these instruments are not museum pieces but tools meant to be played, heard, and trusted on stage or in the studio. Our bench has seen everything from stubborn Moogs and fragile ARP boards to polysynths with corroded traces and keyboards that have traveled too many miles. We approach each repair with patience, documentation, and respect for the original design, while making sensible updates only where reliability demands them. Because we are a small team, you work directly with the person handling your instrument, from the first diagnosis to the final calibration. We also advise on maintenance, source hard-to-find parts, and help you decide when a repair is worthwhile. Patchbay exists to keep old synthesizers making new music.

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.
