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 three-person workshop in Rotterdam dedicated to keeping vintage synthesizers alive. We work on the machines that shaped electronic music — analog polysynths, temperamental drum machines, early digital oddities — replacing tired capacitors, rebuilding keybeds, and coaxing silent oscillators back into tune.
Between us we bring decades of experience in electronics, instrument design, and music-making, but what unites us is simpler: we believe these machines were built to be played, not displayed. Every repair happens by hand at our benches, with period-correct components wherever possible and thoughtful modern solutions where reliability demands it. We test everything the only way that matters — by listening.
Whether your Juno has lost a voice, your 808 has lost its kick, or a flea-market find needs a full restoration, we treat each instrument as if it were heading back to a studio, a stage, and a long life of making noise. Because it is.
