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 repairing vintage synthesizers. We work carefully, one instrument at a time, because old machines deserve patience. Our bench is crowded with test leads, spare knobs, tired capacitors, and service manuals held together by tape. Every repair begins with listening. We power up the synth, play a few notes, and trace the fault by ear before opening the case. Perhaps the filter drifts as it warms. Maybe a voice cuts out, or the envelope behaves strangely. We clean contacts, replace components only when necessary, and keep original parts wherever possible. We believe repair is a form of preservation. These instruments were built to be played for decades, not replaced when something small fails. Rotterdam has a long history of making and fixing things, and we are proud to continue that tradition. Bring us your beloved keyboard, and we will see what can be saved.
Patchbay is a three-person studio in Rotterdam devoted to keeping vintage synthesizers alive, playable, and full of character. We work on instruments that have spent decades in studios, bedrooms, and tour cases, and we believe each one deserves more than a quick fix. From drifting oscillators and noisy sliders to tired keybeds and mysterious faults, we take the time to listen, diagnose, and repair with care.
Our approach combines patient troubleshooting, period-correct components where possible, and a deep respect for the original sound. We do not believe in erasing an instrument’s history; we preserve the quirks that make it worth loving. Whether your synthesizer needs a full overhaul or a little help getting back on stage, you will always know who is working on it and why. Patchbay exists for the joy of switching on an old machine and hearing it come back to life.
