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 three-person studio in Rotterdam, and we spend our days inside vintage synthesizers. We are repair technicians first: we open the cases, replace the leaking capacitors, re-tune the oscillators that have drifted out of pitch, and bring back the filters that went silent decades ago. Our bench is crowded with service manuals, spare chips, and a soldering station that has seen more Moog panels than we can count. We started the studio because we kept meeting musicians whose favourite instruments sat unused in cupboards, not because they were broken beyond saving but because nobody nearby knew how to fix them. We still believe most of these machines can be made to sing again, and we would rather spend an afternoon finding the one bad resistor than see another good synth end up in a skip.
