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 devoted to the repair and restoration of vintage synthesizers. We work on the machines that shaped the sound of the last fifty years — Roland, Moog, Yamaha, Korg, EMS, and the rest — from the rare and legendary to the well-loved and well-worn.
We started the studio because these instruments matter. They were built to be repaired, with discrete components, schematics, and construction that reward patience and care. Somewhere along the way, that way of making things fell out of fashion. We think it's worth keeping alive.
Every synthesizer that comes through our door is treated the same way: carefully diagnosed, honestly assessed, and repaired with respect for its original character. No unnecessary modifications, no shortcuts that compromise the instrument. Whether it's a failed voice chip, a dead key, or years of dust and neglect, our job is to put the machine back in the hands of the people who play it.
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.
