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 devoted to repairing vintage synthesizers and keeping electronic instruments alive. We work with analog and digital keyboards, drum machines, and modular systems, restoring worn circuits, replacing fragile components, and returning each machine to reliable musical use. Our small team combines careful technical work with genuine respect for the instruments that shaped decades of music. Whether an instrument needs a routine service, a difficult diagnosis, or a full restoration, we approach it with patience, clear communication, and attention to detail. We believe these machines are not just equipment; they are tools with history, character, and sound worth preserving. Based in Rotterdam, we serve musicians, collectors, and studios who want their gear maintained properly and played again. At Patchbay, every repair is treated as a collaboration between craft and music, ensuring that classic synthesizers continue to inspire new sounds for years to come.
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.
