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 dedicated to the repair and restoration of vintage synthesizers. We spend our days with soldering irons and oscilloscopes, coaxing life back into instruments that were built to last and mostly did, until they didn't.
Between us we cover decades of combined experience with analog and early digital circuitry, from the classics of Roland, Korg, Moog, and ARP to the odd, wonderful machines that never made it big. We treat every repair with the same care, whether it's a flagship polysynth or a broken drum machine with a devoted following.
Our workshop sits in the west of the city. You're welcome to visit — bring the instrument, bring the story behind it. We like hearing both.
What we don't know we research, and what we can't source we sometimes fabricate. Nothing gets written off before we've tried.
