Patchbay is a three-person studio in Rotterdam devoted to the repair and restoration of vintage synthesizers. We work on the machines that shaped the sound of the last fifty years — Roland, Moog, Yamaha, Korg, EMS, and the rest — from the rare and legendary to the well-loved and well-worn.

We started the studio because these instruments matter. They were built to be repaired, with discrete components, schematics, and construction that reward patience and care. Somewhere along the way, that way of making things fell out of fashion. We think it's worth keeping alive.

Every synthesizer that comes through our door is treated the same way: carefully diagnosed, honestly assessed, and repaired with respect for its original character. No unnecessary modifications, no shortcuts that compromise the instrument. Whether it's a failed voice chip, a dead key, or years of dust and neglect, our job is to put the machine back in the hands of the people who play it.

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.
