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 repairing vintage synthesizers. We work with instruments that have been played, carried, opened up, and passed from one owner to the next. Each arrives with its own history and its own set of quirks, so we begin by listening carefully and tracing the problem before reaching for a fix.

Our work ranges from straightforward maintenance to deeper electronic repairs. We clean, test, diagnose, and restore with the aim of making a synthesizer reliable again while respecting the design that gives it its voice. When a repair calls for a replacement part, we look for a solution that fits the instrument rather than treating it as disposable.

Patchbay is run by three people who share a curiosity about how these machines work and a respect for the sounds they make. We believe a well-cared-for synthesizer has plenty more music in it, and we’re here to help it find its way back into someone’s hands.
