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 devoted to repairing vintage synthesizers. We work with instruments that have been played, carried, opened up, and passed from one owner to the next. Each arrives with its own history and its own set of quirks, so we begin by listening carefully and tracing the problem before reaching for a fix.
Our work ranges from straightforward maintenance to deeper electronic repairs. We clean, test, diagnose, and restore with the aim of making a synthesizer reliable again while respecting the design that gives it its voice. When a repair calls for a replacement part, we look for a solution that fits the instrument rather than treating it as disposable.
Patchbay is run by three people who share a curiosity about how these machines work and a respect for the sounds they make. We believe a well-cared-for synthesizer has plenty more music in it, and we’re here to help it find its way back into someone’s hands.
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.
