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 three-person studio in Rotterdam, dedicated to repairing vintage synthesizers and keeping them in use.
Old instruments have a way of becoming familiar: the feel of a key, the response of a filter, the particular sound a circuit makes when it’s working as it should. When something goes wrong, we take the time to understand both the fault and the instrument around it. We work carefully, preserving original parts wherever practical and making repairs with the long term in mind.
Our studio brings together a shared interest in electronics, sound and the machines that connect them. Whether a synthesizer has a stubborn key, a noisy output or has been silent for years, we’re interested in finding a way forward.
We work with musicians, collectors and anyone who wants to hear an old instrument come to life again. If you have a synth that needs attention, we’d be glad to hear about it.
Patchbay is a small workshop in Rotterdam where three of us spend our days bringing vintage synthesizers back to life. We repair and restore instruments from the 1960s, 70s, and 80s — Minimoogs with drifting oscillators, Junos with silent choruses, Prophet-5s that have not powered on in decades — tracing faults board by board, replacing tired components, and calibrating each machine until it sounds musical again. We believe these instruments were built to be played, not preserved behind glass, so we work carefully and reversibly wherever possible, documenting every repair and keeping original parts when they can be saved. Musicians, studios, and collectors bring us synths from across Europe, sometimes in flight cases, sometimes in pieces. Whether it needs a full restoration or a single sticky key, we treat it as if it were our own, and we will not send it home until we would happily play it ourselves.
