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 compact, three-person workshop rooted in the dynamic streets of Rotterdam, born from a shared reverence for analog sound. Our team shares an unwavering dedication to vintage synthesizers, viewing each oscillator, filter, and routing cable as a vital piece of sonic history waiting to be restored. Whether diagnosing a failing voltage regulator or carefully retrofitting obsolete components, we take immense pride in bringing classic instruments back to their full potential. In our studio, repairing isn't just a technical service—it is a shared passion among friends who believe the past deserves to keep playing. We meticulously diagnose and revive legacy synths, ensuring the iconic sounds of yesterday continue shaping today’s electronic music. Bring us your dented, broken machines, and let us help you reconnect them with the rich, unmistakable sounds they were always meant to make. Every patch, every knob, every fleeting tone depends on the work we do here.
Patchbay is a small repair studio in Rotterdam dedicated to keeping vintage synthesizers alive. We are three people — a technician, a historian, and a musician — who believe that the instruments built in the 1960s, 70s, and 80s still have decades of sound left in them, if someone is willing to care for them properly.
We work on everything from early Moogs and Arps to Roland Junos and Oberheim OB-series, handling everything from dead power supplies and leaky batteries to full recaps and voice board restoration. Our workshop is small by design. We take on a limited number of instruments at a time, which means every synth that comes through our door gets our full attention.
Most of our clients are working musicians, collectors, and small studios across Europe, but we also welcome instruments with stories we'd love to hear. If you have a piece of synth history that needs care, we'd be glad to talk.
