Patchbay is a three-person studio in Rotterdam dedicated to bringing vintage synthesizers back to life. We repair analog and digital instruments that shaped the sound of music, from classic drum machines and polyphonic synths to quirky, characterful machines that rarely leave a musician’s side. Our work combines technical knowledge with respect for each instrument’s history, because a synth is more than a circuit board: it carries the decisions, compromises, and personality of its original design. We diagnose faults, restore unreliable voices, and carefully service aging components without erasing the character that made an instrument worth keeping. Whether a machine has been silent for years or simply needs a thoughtful tune-up, we treat every repair as a careful act of restoration. Based in Rotterdam, Patchbay works with musicians, studios, collectors, and anyone who believes electronic instruments deserve another chapter. We restore them to sound as they should, preserving the details that make each one unique.
