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 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.
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.
