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, keeping vintage synthesizers in working hands. We repair the instruments that have picked up a crackle, lost a voice, drifted out of tune, or stopped making sound altogether.
We like the patient side of repair: tracing a fault, understanding an old circuit, and finding the right fix rather than the quickest workaround. Our aim is to make each instrument dependable without sanding away the character that made someone fall for it in the first place.
Some synths arrive with a clear problem. Others come with a story and a noise that only happens after twenty minutes. Either way, the work starts with listening—to the instrument and to the person who plays it.
We’re a small studio by choice. It keeps us close to the work, and to the musicians who trust us with something they want to keep making music with.
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.
