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.

Patchbay is a three-person studio in Rotterdam devoted to keeping vintage synthesizers making the sounds they were built to make. We repair, service and restore analog instruments from the late 1960s onward, from familiar Moogs and ARPs to oddities with no service manual. Every synth that comes through the door is treated as a working instrument rather than a museum piece. We trace faults, rebuild power supplies, refresh capacitors, clean keybeds and calibrate oscillators, always with an eye on reliability and the character that made the machine worth saving. We document what we do, explain the options clearly and never replace more than necessary. Whether you need one dead voice brought back or a full restoration, we work carefully, at the bench and in conversation with you. Old synths belong on records and stages, and our job is to keep them there.
