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 is a three-person repair studio in Rotterdam dedicated to vintage synthesizers. We work on analog circuits, replace failing capacitors and resistors, calibrate unstable oscillators, and restore instruments that have been silent for years. Our bench sees early Japanese mono synths, European string machines, American polys, and large modular systems. We treat each repair as a specific problem rather than a routine job, because these machines were built differently and fail differently. The studio grew out of our own need for careful, local repairs. Over time, musicians, collectors, and producers across the Netherlands started bringing us gear they could not trust elsewhere. We open every case with the same approach: diagnose the fault properly, use appropriate parts, and test the result thoroughly. We do not apply quick fixes or ignore underlying issues. Whether your synthesizer suffers from tuning drift, dead voices, noisy outputs, or an unknown electrical fault, we are in Rotterdam to find the cause and return it to reliable working condition.
