Patchbay is a three-person studio tucked into a quiet corner of Rotterdam, dedicated to repairing vintage synthesizers. We work on instruments from the seventies and eighties—Moog, Roland, Sequential, ARP—and everything in between, from stubborn oscillator drift to full restorations of boards untouched for decades. Each synth that crosses our bench has a history, and we treat it like one. We trace circuits, replace capacitors, clean contacts, and recalibrate pitch with patience rather than shortcuts, because these machines deserve better than quick fixes. Beyond repairs, we help musicians find the right instrument, advise on maintenance, and occasionally rescue projects others have given up on. We are three people, one shared workbench, and a wall of drawers filled with obsolete parts we refuse to throw away. If your synthesizer has stopped singing, bring it by. We'll listen to what it's telling us, and we'll get it back in tune.
