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 began in a small, cluttered workshop in Rotterdam, where solder smoke and old capacitors seem to belong together. We are a three-person studio, which means every synthesizer that comes through our door is handled by one of the same people who started the project. No call center, no hand-off to strangers. We repair vintage synthesizers: the dusty analog beasts, the rare oddities, the ones with missing knobs and mysterious tuning drift. Our work is part electronics, part archaeology, part stubborn love. We listen to the hum before we open the case, and we believe most vintage synths are not dead, just waiting for someone to pay attention. In a city known for moving quickly, we prefer taking our time. Patchbay exists to keep old voices alive, one oscillator, filter, and power supply at a time. If you have a synth that sings, whispers, or hums through the decades, we would be glad to meet it.
Patchbay began in a narrow workshop on the edge of Rotterdam’s Noord district, where the hum of aging oscillators meets the rhythm of the city’s canals. Founded by three synth enthusiasts — a former studio engineer, a circuit designer, and a musician who still plays the same Juno‑106 he bought in 1986 — the studio grew from late‑night repair sessions into a dedicated space for restoring the instruments that shaped electronic music’s golden era. Every unit that passes through our bench is treated with the same reverence we give a first‑press vinyl: capacitors are swapped, contacts cleaned, and calibration traced back to original service manuals. We don’t just fix synthesizers; we listen to their history, understand their quirks, and return them to the stage or studio ready to inspire the next generation of sound. Patchbay is small, intentional, and built on the belief that vintage gear deserves a future as vivid as its past.
