About

Write the opening of the About us page for Patchbay, a three-person studio in Rotterdam that repairs vintage synthesizers. About 150 words.

In a quiet corner of Rotterdam, surrounded by the scent of warm solder and the hum of calibrated oscillators, Patchbay brings classic electronic instruments back to life. We are a three-person studio united by an obsession with vintage synthesizers and the belief that these machines belong under musicians' hands, not gathering dust in storage.

Every synthesizer that crosses our workbench carries decades of history, along with brittle capacitors, worn contacts, and drifting tuning. Whether we are facing a temperamental analog polysynth from the seventies or an early digital classic, we approach each repair with patience and precision. We do not believe in quick fixes. Instead, we study original schematics, source elusive components, and meticulously restore every circuit, keybed, and fader until the instrument plays as reliably as the day it was built. Patchbay exists to keep these irreplaceable voices singing for the next generation of artists.

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.
