About

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

Tucked away in a bright workshop near the Rotterdam docks, Patchbay is a three-person studio dedicated to keeping electronic music history alive. We repair, restore, and calibrate vintage synthesizers, drum machines, and outboard gear. Whether it is a temperamental Juno with failing voice chips, a road-worn Minimoog drifting out of tune, or an obscure polysynth needing a complete overhaul, our benches are built for machines that make noise.

Between the three of us, we combine decades of experience in electronics, sound design, and obsessive troubleshooting. We do not view classic synthesizers as fragile museum pieces meant to sit behind glass; they are working instruments built to be played, patched, and pushed to their limits. Armed with original schematics, precision test gear, and a deep respect for analog circuitry, we bring tired hardware back from the brink—ready for another forty years in the studio or on stage.

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.
