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.
