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 began the way most repair shops do: with a broken synth, a stubborn owner, and a soldering iron that refused to stay idle. We're three people—Joris, Marit, and Tomas—working out of a small workshop on the back streets of Rotterdam-Noord, surrounded by oscilloscopes, spare parts, and instruments that sometimes arrive in worse condition than their owners admit.

Between us, we've spent decades repairing and restoring vintage synthesizers: Rolands, Moogs, Korgs, Yamahas, and machines whose manuals were never written in the first place. We don't sell anything. We fix things. That focus keeps us honest and keeps the work slow, careful, and done properly.

We believe old instruments deserve to keep making music, not gather dust in attics or fetch prices only collectors can pay. Whether it's a cracked keybed, a dying power supply, or a voice that's gone quiet, we'd like to help bring it back.
