Hy4 vs Gemini 3.8 Flash

Patchbay is a three-person studio in Rotterdam repairing vintage synthesizers and the odd drum machine or piece of studio equipment. We look after instruments that have survived tours, basements, and years of silence in cupboards. Our task is not to make them new, but to make them dependable while keeping the character that made them worth saving.

Every repair starts with listening: to the fault, to the owner, and to the instrument itself. From there we diagnose carefully, solder cleanly, calibrate patiently, and replace parts only when necessary. Between us we bring electronics, restoration, design, and studio experience, which keeps the work practical, unhurried, and attentive to small details. We document what we find, source components with care, and explain the work in plain language. Some jobs take an afternoon; others become long conversations with forty-year-old circuits. In each case, the goal is simple: return the machine to the hands, recordings, and rooms where it belongs.

Tucked away in Rotterdam, Patchbay is a three-person repair studio dedicated to the preservation and revival of vintage synthesizers. We believe that classic instruments are living machines rather than museum relics—tools built to inspire, create, and be played loud. Between the three of us, we combine decades of experience in electronics engineering, sound design, and meticulous craftsmanship. Whether tracking down elusive voice chips for an eighties polyphonic giant, rebuilding power supplies, or recalibrating the drift on a cantankerous monophonic circuit from the seventies, we treat every piece of gear with obsessive attention to detail. Our workbench is built on a deep respect for historical engineering and a refusal to cut corners. For musicians, producers, and collectors across the Netherlands and beyond, Patchbay is where forgotten circuits find their current again, keeping the tactile soul of analog synthesis alive and resonant.
