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 three people in a workshop in Rotterdam, trying to keep old synthesizers alive. We repair, restore and recalibrate the instruments that shaped electronic music: Moogs and Oberheims, Rolands and Sequential Circuits, the odd temperamental Soviet oddity that someone found in an attic.
Most of what lands on our benches has been silent for years. A crackling pot, a drifting oscillator, a power supply that gave up in 1994. Some come from working musicians who need their instrument back before the next tour. Others come from people who inherited a dusty box from a parent and want to hear what it sounds like.
We work slowly and by hand. We trace faults with a scope and a schematic, source or rebuild parts when originals are gone, and change as little as we can. Every synth leaves with a note describing exactly what we did, so the next person to open it knows where we have been.
Come by, bring your synth, and stay for coffee.
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.
