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 repairing vintage synthesizers and keeping them in use.
Old instruments have a way of becoming familiar: the feel of a key, the response of a filter, the particular sound a circuit makes when it’s working as it should. When something goes wrong, we take the time to understand both the fault and the instrument around it. We work carefully, preserving original parts wherever practical and making repairs with the long term in mind.
Our studio brings together a shared interest in electronics, sound and the machines that connect them. Whether a synthesizer has a stubborn key, a noisy output or has been silent for years, we’re interested in finding a way forward.
We work with musicians, collectors and anyone who wants to hear an old instrument come to life again. If you have a synth that needs attention, we’d be glad to hear about 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.
