About

Write the opening of the About us page for Patchbay, a three-person studio in Rotterdam that repairs vintage synthesizers. About 150 words.

Welcome to Patchbay. A dedicated three-person studio in Rotterdam, where analog warmth meets modern precision. Our workshop is a sanctuary for vintage synthesizers, circuit boards, and forgotten sounds. We operate on the belief that vintage gear deserves respect and careful handling. Every unit we restore is given a new life, preserving its unique character while ensuring it functions reliably. We work meticulously on instruments that shaped electronic music history. This isn't just repair; it is resurrection. Our artisans take the time to solder every connection and clean every capacitor, understanding that imperfections hold stories worth keeping. We aim to keep the legacy of analog synthesis alive. Whether you need a fix or advice on your collection's condition, we support the analog revival. Trust in our expertise to get your dreams humming again. In a digital world, we choose to sound the truth. We believe in the tangible sound of history.

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.
