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 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.
Patchbay is a three-person studio in Rotterdam devoted to the repair of vintage synthesizers. We work on instruments that have already lived a long life on stages, in studios, and in spare rooms, and we treat each one as something worth keeping rather than replacing. Our benches are set up for careful diagnosis, component-level repair, and the slow work of bringing an old circuit back into reliable use.
The three of us share the shop, the tools, and the jobs. One person may trace a failing voice while another sources a part or recalibrates an oscillator; we pass instruments between us until the sound is right and the hardware is stable. Clients come to us with analog polys, early digital machines, drum boxes, and the odd modular that has been patched and repatched for decades. We listen first, then open the case.
We are not a museum and we are not a showroom. Patchbay exists so that working musicians, collectors, and curious owners in Rotterdam and beyond can keep playing the instruments they already love.
