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 workshop based in Rotterdam, dedicated to keeping vintage synthesizers alive and playable. We are technicians, musicians, and obsessive tinkerers who believe that classic analog instruments deserve better than silence. From temperamental Jupiter-8s to worn-out ARP Odysseys, we restore, repair, and maintain the machines that shaped the sound of modern music. Every repair starts with listening—both to the instrument and to the person who plays it. Whether you are chasing a rare fault, need a full calibration, or simply want your old synth to feel new again, our bench is open. We understand that no two synthesizers arrive with the same story, and we treat each circuit, slider, and key with the care its history deserves. At Patchbay, we are here to make sure the sounds of tomorrow are built on those that came before.
Patchbay is a three-person studio in Rotterdam dedicated to the repair and restoration of vintage synthesizers. We spend our days with soldering irons and oscilloscopes, coaxing life back into instruments that were built to last and mostly did, until they didn't.
Between us we cover decades of combined experience with analog and early digital circuitry, from the classics of Roland, Korg, Moog, and ARP to the odd, wonderful machines that never made it big. We treat every repair with the same care, whether it's a flagship polysynth or a broken drum machine with a devoted following.
Our workshop sits in the west of the city. You're welcome to visit — bring the instrument, bring the story behind it. We like hearing both.
What we don't know we research, and what we can't source we sometimes fabricate. Nothing gets written off before we've tried.
