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, dedicated to repairing vintage synthesizers and keeping them in use.
Old instruments have a way of becoming familiar: the feel of a key, the response of a filter, the particular sound a circuit makes when it’s working as it should. When something goes wrong, we take the time to understand both the fault and the instrument around it. We work carefully, preserving original parts wherever practical and making repairs with the long term in mind.
Our studio brings together a shared interest in electronics, sound and the machines that connect them. Whether a synthesizer has a stubborn key, a noisy output or has been silent for years, we’re interested in finding a way forward.
We work with musicians, collectors and anyone who wants to hear an old instrument come to life again. If you have a synth that needs attention, we’d be glad to hear about it.
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.
