Gemini 4 Argon vs GLM 5.3

In a quiet industrial building overlooking the Maas, the air smells of warm dust, solder flux, and ozone. This is Patchbay, a three-person workshop in Rotterdam dedicated to keeping the golden age of electronic music alive. We don’t view vintage synthesizers as museum pieces to be locked behind glass. To us, a Roland Jupiter-8 or an ARP Odyssey is a living, breathing instrument meant to be played, gigged, and pushed to its sonic limits.

Between the three of us, we have spent decades deciphering faded schematics, hunting down obsolete transistors, and cleaning decades of club grime from beneath weighted keys. Rotterdam is a city built on raw electronics and relentless rhythms, and we take pride in keeping its hardware running. Whether you bring us a touring workhorse with a dead voice chip or a garage-find modular rig that hasn’t powered on since 1984, we are here to make it sing again.

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.
