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.
