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 the repair and restoration of vintage synthesizers. We are engineers, musicians, and collectors who believe these instruments are not museum pieces but tools meant to be played, heard, and trusted on stage or in the studio. Our bench has seen everything from stubborn Moogs and fragile ARP boards to polysynths with corroded traces and keyboards that have traveled too many miles. We approach each repair with patience, documentation, and respect for the original design, while making sensible updates only where reliability demands them. Because we are a small team, you work directly with the person handling your instrument, from the first diagnosis to the final calibration. We also advise on maintenance, source hard-to-find parts, and help you decide when a repair is worthwhile. Patchbay exists to keep old synthesizers making new music.
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.
