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 dedicated to the repair and restoration of vintage synthesizers. We work on instruments that have been sitting in attics, basements, and rehearsal rooms for decades — the ones that hum when they shouldn't, lose their voice, or refuse to power on at all. Our approach is patient and detail-oriented. We trace faults through aging circuit boards, source period-correct components when possible, and treat every repair as a conversation with the person who built the instrument, and the musicians who played it before it fell silent.

We believe these machines deserve to stay in circulation rather than end up in landfill. Whether it is a Moog, a Juno, or a machine you cannot name, bring it in and we will tell you honestly what it needs.

Patchbay is a three-person workshop in Rotterdam where vintage synthesizers come back to life. Whatever lands on our bench — a battered Minimoog, a Juno with dead keys, an ARP silent since the eighties — gets the same treatment: careful diagnosis, honest advice, and repairs done right.

We started Patchbay because we believe a good synthesizer shouldn't die of old age. These machines are more than circuits and sliders — they're the sound of records you grew up with, and the reason some of us got into music in the first place. Every one we fix goes back out into the world ready to make more.

Between us we handle everything from recapping and calibration to keybed work and the hunt for parts nobody has made in decades. It's slow, meticulous work, and we like it that way. If something in your collection hums, crackles, or refuses to turn on, bring it in — we'll see what we can do.
