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 three people in a narrow workshop near the Maas in Rotterdam. Every day we open up instruments that were built before most of their current owners were born. Some arrive in flight cases and some come wrapped in old bath towels. Most have a story: a Juno that went quiet halfway through a gig, a Minimoog left in someone's attic for thirty years, or a modular system that a previous technician gave up on.
We started Patchbay because we kept seeing good synthesizers sent off as "unrepairable" when all they needed was patience, a schematic and a steady hand. We swap out dried capacitors, hunt for intermittent faults, recalibrate oscillators until they track properly again, and source or rebuild parts that stopped being made decades ago.
We don't try to make old machines sound new. Our job is to make them sound like themselves again, and to make sure they keep working for the next person who plays them.
