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, and we spend our days inside vintage synthesizers. We are repair technicians first: we open the cases, replace the leaking capacitors, re-tune the oscillators that have drifted out of pitch, and bring back the filters that went silent decades ago. Our bench is crowded with service manuals, spare chips, and a soldering station that has seen more Moog panels than we can count. We started the studio because we kept meeting musicians whose favourite instruments sat unused in cupboards, not because they were broken beyond saving but because nobody nearby knew how to fix them. We still believe most of these machines can be made to sing again, and we would rather spend an afternoon finding the one bad resistor than see another good synth end up in a skip.
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.
