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, 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.
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.
