About
Write the opening of the About us page for Patchbay, a three-person studio in Rotterdam that repairs vintage synthesizers. About 150 words.
Some of the machines we work on were built before any of us were born. Patchbay is a three-person repair studio in Rotterdam, and what we do is simple to describe: we keep vintage synthesizers playing. A Minimoog that sat in an attic for thirty years. A Juno-60 with keys that no longer speak. A modular system that hums where it should roar. Whatever comes through our door gets opened up, traced through, and brought back.
That means rebuilding power supplies, cleaning a thousand key contacts, chasing a fault across three boards until it turns out to be a single cracked solder joint. It means calibrating oscillators that have drifted for decades, and listening — really listening — until a filter sounds the way it did the day it left the factory.
We do this because these instruments still sound like nothing else, and because somewhere a player is waiting to hear one come back to life.
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.
