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 compact, three-person workshop rooted in the dynamic streets of Rotterdam, born from a shared reverence for analog sound. Our team shares an unwavering dedication to vintage synthesizers, viewing each oscillator, filter, and routing cable as a vital piece of sonic history waiting to be restored. Whether diagnosing a failing voltage regulator or carefully retrofitting obsolete components, we take immense pride in bringing classic instruments back to their full potential. In our studio, repairing isn't just a technical service—it is a shared passion among friends who believe the past deserves to keep playing. We meticulously diagnose and revive legacy synths, ensuring the iconic sounds of yesterday continue shaping today’s electronic music. Bring us your dented, broken machines, and let us help you reconnect them with the rich, unmistakable sounds they were always meant to make. Every patch, every knob, every fleeting tone depends on the work we do here.
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.
