Hy4 vs Claude Haiku 5.5

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.

Patchbay is a three-person studio in Rotterdam, and we spend our days inside vintage synthesizers. We are repair technicians first: we open the cases, replace the leaking capacitors, re-tune the oscillators that have drifted out of pitch, and bring back the filters that went silent decades ago. Our bench is crowded with service manuals, spare chips, and a soldering station that has seen more Moog panels than we can count. We started the studio because we kept meeting musicians whose favourite instruments sat unused in cupboards, not because they were broken beyond saving but because nobody nearby knew how to fix them. We still believe most of these machines can be made to sing again, and we would rather spend an afternoon finding the one bad resistor than see another good synth end up in a skip.
