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, keeping vintage synthesizers in working hands. We repair the instruments that have picked up a crackle, lost a voice, drifted out of tune, or stopped making sound altogether.
We like the patient side of repair: tracing a fault, understanding an old circuit, and finding the right fix rather than the quickest workaround. Our aim is to make each instrument dependable without sanding away the character that made someone fall for it in the first place.
Some synths arrive with a clear problem. Others come with a story and a noise that only happens after twenty minutes. Either way, the work starts with listening—to the instrument and to the person who plays it.
We’re a small studio by choice. It keeps us close to the work, and to the musicians who trust us with something they want to keep making music with.
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.
