Hy4Tencent

Patchbay is a three-person studio in Rotterdam repairing vintage synthesizers and the odd drum machine or piece of studio equipment. We look after instruments that have survived tours, basements, and years of silence in cupboards. Our task is not to make them new, but to make them dependable while keeping the character that made them worth saving.

Every repair starts with listening: to the fault, to the owner, and to the instrument itself. From there we diagnose carefully, solder cleanly, calibrate patiently, and replace parts only when necessary. Between us we bring electronics, restoration, design, and studio experience, which keeps the work practical, unhurried, and attentive to small details. We document what we find, source components with care, and explain the work in plain language. Some jobs take an afternoon; others become long conversations with forty-year-old circuits. In each case, the goal is simple: return the machine to the hands, recordings, and rooms where it belongs.
