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 industrial building overlooking the Maas, the air smells of warm dust, solder flux, and ozone. This is Patchbay, a three-person workshop in Rotterdam dedicated to keeping the golden age of electronic music alive. We don’t view vintage synthesizers as museum pieces to be locked behind glass. To us, a Roland Jupiter-8 or an ARP Odyssey is a living, breathing instrument meant to be played, gigged, and pushed to its sonic limits.
Between the three of us, we have spent decades deciphering faded schematics, hunting down obsolete transistors, and cleaning decades of club grime from beneath weighted keys. Rotterdam is a city built on raw electronics and relentless rhythms, and we take pride in keeping its hardware running. Whether you bring us a touring workhorse with a dead voice chip or a garage-find modular rig that hasn’t powered on since 1984, we are here to make it sing again.
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.
