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 devoted to the repair of vintage synthesizers. We work on instruments that have already lived a long life on stages, in studios, and in spare rooms, and we treat each one as something worth keeping rather than replacing. Our benches are set up for careful diagnosis, component-level repair, and the slow work of bringing an old circuit back into reliable use.

The three of us share the shop, the tools, and the jobs. One person may trace a failing voice while another sources a part or recalibrates an oscillator; we pass instruments between us until the sound is right and the hardware is stable. Clients come to us with analog polys, early digital machines, drum boxes, and the odd modular that has been patched and repatched for decades. We listen first, then open the case.

We are not a museum and we are not a showroom. Patchbay exists so that working musicians, collectors, and curious owners in Rotterdam and beyond can keep playing the instruments they already love.

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.
