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 small studio in Rotterdam where vintage synthesizers come back to life. We are three technicians, musicians and longtime collectors who have spent the last decade trading schematics, hunting spare parts, and learning the quirks of every oscillator and filter that has passed through our hands.
What started as helping friends keep their Junos and ARPs in tune has grown into a dedicated workshop in the north of the city. We repair, restore and service instruments from the sixties to the early nineties, from well-known classics to rare prototypes that barely left the factory.
We believe these machines are more than equipment. They carry histories, imperfections and sounds that cannot be replaced. Our job is to respect that character while making sure each instrument is reliable, playable, and ready for another lifetime of 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.
