About
Write the opening of the About us page for Patchbay, a three-person studio in Rotterdam that repairs vintage synthesizers. About 150 words.
Tucked away in Rotterdam, Patchbay is a three-person repair studio dedicated to the preservation and revival of vintage synthesizers. We believe that classic instruments are living machines rather than museum relics—tools built to inspire, create, and be played loud. Between the three of us, we combine decades of experience in electronics engineering, sound design, and meticulous craftsmanship. Whether tracking down elusive voice chips for an eighties polyphonic giant, rebuilding power supplies, or recalibrating the drift on a cantankerous monophonic circuit from the seventies, we treat every piece of gear with obsessive attention to detail. Our workbench is built on a deep respect for historical engineering and a refusal to cut corners. For musicians, producers, and collectors across the Netherlands and beyond, Patchbay is where forgotten circuits find their current again, keeping the tactile soul of analog synthesis alive and resonant.
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.
