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 repairing vintage synthesizers. We work on the instruments that have shaped decades of music, from well-loved studio staples to curious machines that have spent years in storage.
Old synthesizers develop problems in their own ways. A key stops responding, a filter drifts, a power supply gives out. We take the time to trace the fault, understand the instrument and make a repair that respects how it was built. Wherever possible, we preserve original components; when a part needs replacing, we choose with care.
We know these instruments are more than collections of circuits. They carry sounds, habits and memories, and each one has a story before it reaches our bench. Whether you rely on yours every day or are hoping to hear it again after a long silence, our aim is to help you get back to making music.
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.
