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 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.
Patchbay is a three-person studio in Rotterdam devoted to the restoration and repair of vintage synthesizers. We believe analog gear holds a living voice, and our purpose is to safeguard that sound for musicians, collectors, and creators who value authenticity. With hands-on experience in circuitry, voltage calibration, and component preservation, we treat every console, drum machine, or modular voice with meticulous care. Rotterdam’s eclectic artistic community fuels our commitment to keeping analog heritage alive, bridging past technology with present music. Whether rescuing a neglected lab unit or reviving a cherished polysynth, we approach each instrument as a unique piece of musical history, ensuring it performs as intended for years ahead. We love helping artists reconnect with the warmth and character only vintage hardware can offer. Our workshop sits in the heart of the city, where dusty circuit boards meet fresh compositions, and every repaired synth becomes part of a new musical story.
