Patchbay is three people and a bench in Rotterdam. We repair vintage synthesizers of all kinds, from a Moog that needs one capacitor to a modular system that hasn't been run in thirty years.

We started because older instruments deserve to keep working. The circuitry is simple, but the failures are personal: a dead pot in a favourite key, a CV rail that drifts, a ribbon controller that was saturated in smoke. We treat each case the way our own instruments would need to be treated.

A workshop is a good place for slow work and long conversations. We're always glad to open a system on the bench, find out what it actually needs, and explain why. If you have something unwell, send it over or come visit us in Rotterdam.

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.
