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 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.

Patchbay is een drie personen studio in Rotterdam die zich specialiseert in het repareren van vintage synthesizers. Onze missie is om de magie van klassieke elektronische instrumenten levendig te houden en te delen met een nieuwe generatie makers en musicians.

Gestart door twee ervaren technici en een ontwerper, combineren wij technische precisie met een diep begrip van elektronische muziekgeschiedenis. Wij geloven dat elk oud apparaat een verhaal heeft en een unieke klank die bijdragen aan de creatieve processen van artiesten.

Onze aanpak is zorgvuldig en respectvol. Elk apparaat wordt met de grootste zorg behandeld, met gebruik van oorspronkelijke onderdelen wanneer mogelijk en moderne technieken wanneer nodig. We streven altijd naar een perfecte balans tussen authenticiteit en betrouwbaarheid.

Of je nu een geliefde vintage synth moet repareren of hulp nodig hebt bij het onderhouden van je collectie, Patchbay staat klaar om je instrumenten weer in geluid te brengen. Neem contact op voor een consult; wij kijken uit naar het horen van je project.
