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 dedicated to repairing vintage synthesizers. We work on the instruments that have shaped decades of music, from well-loved studio staples to curious machines that have spent years in storage.
Old synthesizers develop problems in their own ways. A key stops responding, a filter drifts, a power supply gives out. We take the time to trace the fault, understand the instrument and make a repair that respects how it was built. Wherever possible, we preserve original components; when a part needs replacing, we choose with care.
We know these instruments are more than collections of circuits. They carry sounds, habits and memories, and each one has a story before it reaches our bench. Whether you rely on yours every day or are hoping to hear it again after a long silence, our aim is to help you get back to making music.
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.
