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 began in a cluttered apartment in Rotterdam, where three friends spent weekends coaxing old synthesizers back to life. What started as a shared obsession quickly outgrew the living room. In 2016, we opened our first proper workshop in a converted warehouse on the south side of the city, and we have been soldering, calibrating, and listening closely ever since.
We are a small team of three. Niels handles the analog work, coaxing warm tones from aging oscillators and reluctant filters. Marijn focuses on digital systems and the occasional stubborn MIDI quirk. Sanna manages restorations, sourcing rare components and keeping long projects on track. Between us, we have decades of experience with the machines that shaped electronic music.
Every synth that passes through our doors carries decades of sound inside it. Our job is to make sure that story continues.
