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 repairing vintage synthesizers. We work with instruments that have been played, carried, opened up, and passed from one owner to the next. Each arrives with its own history and its own set of quirks, so we begin by listening carefully and tracing the problem before reaching for a fix.
Our work ranges from straightforward maintenance to deeper electronic repairs. We clean, test, diagnose, and restore with the aim of making a synthesizer reliable again while respecting the design that gives it its voice. When a repair calls for a replacement part, we look for a solution that fits the instrument rather than treating it as disposable.
Patchbay is run by three people who share a curiosity about how these machines work and a respect for the sounds they make. We believe a well-cared-for synthesizer has plenty more music in it, and we’re here to help it find its way back into someone’s hands.
