About

Write the opening of the About us page for Patchbay, a three-person studio in Rotterdam that repairs vintage synthesizers. About 150 words.

Tucked away in Rotterdam, Patchbay is a three-person repair studio dedicated to the preservation and revival of vintage synthesizers. We believe that classic instruments are living machines rather than museum relics—tools built to inspire, create, and be played loud. Between the three of us, we combine decades of experience in electronics engineering, sound design, and meticulous craftsmanship. Whether tracking down elusive voice chips for an eighties polyphonic giant, rebuilding power supplies, or recalibrating the drift on a cantankerous monophonic circuit from the seventies, we treat every piece of gear with obsessive attention to detail. Our workbench is built on a deep respect for historical engineering and a refusal to cut corners. For musicians, producers, and collectors across the Netherlands and beyond, Patchbay is where forgotten circuits find their current again, keeping the tactile soul of analog synthesis alive and resonant.

Patchbay is a small workshop in Rotterdam where old synthesizers come back to life. We are three people — a former recording engineer, a self-taught circuit obsessive, and a classically trained pianist who fell in love with broken machines — and between us we have spent decades coaxing sound out of equipment the rest of the world gave up on.

We started Patchbay because we kept meeting the same problem: beloved instruments sitting silent in attics and studio corners, written off as unfixable. A Juno with a dead voice chip. A Prophet that drifts out of tune. A Moog that hums when it shouldn't. To us, none of these are lost causes. They are instruments with history in them, and they deserve careful hands, original parts where possible, and honest work.

Every synth that leaves our bench is played, tested, and listened to — because that is what it was made for.
