Gemini 4 Carbon vs GLM 5.3

Tucked away in a bright workshop near the Rotterdam docks, Patchbay is a three-person studio dedicated to keeping electronic music history alive. We repair, restore, and calibrate vintage synthesizers, drum machines, and outboard gear. Whether it is a temperamental Juno with failing voice chips, a road-worn Minimoog drifting out of tune, or an obscure polysynth needing a complete overhaul, our benches are built for machines that make noise.

Between the three of us, we combine decades of experience in electronics, sound design, and obsessive troubleshooting. We do not view classic synthesizers as fragile museum pieces meant to sit behind glass; they are working instruments built to be played, patched, and pushed to their limits. Armed with original schematics, precision test gear, and a deep respect for analog circuitry, we bring tired hardware back from the brink—ready for another forty years in the studio or on stage.

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.
