Patchbay is a small repair studio in Rotterdam dedicated to keeping vintage synthesizers alive. We are three people — a technician, a historian, and a musician — who believe that the instruments built in the 1960s, 70s, and 80s still have decades of sound left in them, if someone is willing to care for them properly.

We work on everything from early Moogs and Arps to Roland Junos and Oberheim OB-series, handling everything from dead power supplies and leaky batteries to full recaps and voice board restoration. Our workshop is small by design. We take on a limited number of instruments at a time, which means every synth that comes through our door gets our full attention.

Most of our clients are working musicians, collectors, and small studios across Europe, but we also welcome instruments with stories we'd love to hear. If you have a piece of synth history that needs care, we'd be glad to talk.

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.
