About
Write the opening of the About us page for Patchbay, a three-person studio in Rotterdam that repairs vintage synthesizers. About 150 words.
Patchbay is a three-person studio in Rotterdam dedicated to repairing vintage synthesizers. We work on the instruments that have shaped decades of music, from well-loved studio staples to curious machines that have spent years in storage.
Old synthesizers develop problems in their own ways. A key stops responding, a filter drifts, a power supply gives out. We take the time to trace the fault, understand the instrument and make a repair that respects how it was built. Wherever possible, we preserve original components; when a part needs replacing, we choose with care.
We know these instruments are more than collections of circuits. They carry sounds, habits and memories, and each one has a story before it reaches our bench. Whether you rely on yours every day or are hoping to hear it again after a long silence, our aim is to help you get back to making music.
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.
