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 small repair studio in Rotterdam, built around three hands, one bench, and a shared patience for machines that should have been forgotten. We work on vintage synthesizers — the hissing, glowing, drifting instruments that shaped records decades ago and still find their way to us in boxes, corners, and half-finished projects. Some arrive dead silent. Others howl through cracked pots, sticky keys, and memories of bad rooms. We like that. Our approach is careful: diagnose, restore, and explain what we found. We replace what must be replaced, but we preserve what gives an instrument its character, including its quirks when they are honest ones. Each repair is handled directly by the three of us, from first inspection to final listening. We are not a factory and we do not rush. We are three people in Rotterdam who believe old synthesizers deserve attention, patience, and a little stubborn love.
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.
