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 began the way most repair shops do: with a broken synth, a stubborn owner, and a soldering iron that refused to stay idle. We're three people—Joris, Marit, and Tomas—working out of a small workshop on the back streets of Rotterdam-Noord, surrounded by oscilloscopes, spare parts, and instruments that sometimes arrive in worse condition than their owners admit.
Between us, we've spent decades repairing and restoring vintage synthesizers: Rolands, Moogs, Korgs, Yamahas, and machines whose manuals were never written in the first place. We don't sell anything. We fix things. That focus keeps us honest and keeps the work slow, careful, and done properly.
We believe old instruments deserve to keep making music, not gather dust in attics or fetch prices only collectors can pay. Whether it's a cracked keybed, a dying power supply, or a voice that's gone quiet, we'd like to help bring it back.
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.
