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 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.
Patchbay is a small repair studio in Rotterdam dedicated to keeping vintage synthesizers alive. We are three people — a technician, a historian, and a musician — who believe that the instruments built in the 1960s, 70s, and 80s still have decades of sound left in them, if someone is willing to care for them properly.
We work on everything from early Moogs and Arps to Roland Junos and Oberheim OB-series, handling everything from dead power supplies and leaky batteries to full recaps and voice board restoration. Our workshop is small by design. We take on a limited number of instruments at a time, which means every synth that comes through our door gets our full attention.
Most of our clients are working musicians, collectors, and small studios across Europe, but we also welcome instruments with stories we'd love to hear. If you have a piece of synth history that needs care, we'd be glad to talk.
