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 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.
Patchbay is a three-person studio in Rotterdam devoted to the restoration and repair of vintage synthesizers. We believe analog gear holds a living voice, and our purpose is to safeguard that sound for musicians, collectors, and creators who value authenticity. With hands-on experience in circuitry, voltage calibration, and component preservation, we treat every console, drum machine, or modular voice with meticulous care. Rotterdam’s eclectic artistic community fuels our commitment to keeping analog heritage alive, bridging past technology with present music. Whether rescuing a neglected lab unit or reviving a cherished polysynth, we approach each instrument as a unique piece of musical history, ensuring it performs as intended for years ahead. We love helping artists reconnect with the warmth and character only vintage hardware can offer. Our workshop sits in the heart of the city, where dusty circuit boards meet fresh compositions, and every repaired synth becomes part of a new musical story.
