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 dedicated to keeping vintage synthesizers alive. We are three people — a technician, a historian, and a musician — who believe that the instruments built in the 1960s, 70s, and 80s still have decades of sound left in them, if someone is willing to care for them properly.
We work on everything from early Moogs and Arps to Roland Junos and Oberheim OB-series, handling everything from dead power supplies and leaky batteries to full recaps and voice board restoration. Our workshop is small by design. We take on a limited number of instruments at a time, which means every synth that comes through our door gets our full attention.
Most of our clients are working musicians, collectors, and small studios across Europe, but we also welcome instruments with stories we'd love to hear. If you have a piece of synth history that needs care, we'd be glad to talk.
Some of the machines we work on were built before any of us were born. Patchbay is a three-person repair studio in Rotterdam, and what we do is simple to describe: we keep vintage synthesizers playing. A Minimoog that sat in an attic for thirty years. A Juno-60 with keys that no longer speak. A modular system that hums where it should roar. Whatever comes through our door gets opened up, traced through, and brought back.
That means rebuilding power supplies, cleaning a thousand key contacts, chasing a fault across three boards until it turns out to be a single cracked solder joint. It means calibrating oscillators that have drifted for decades, and listening — really listening — until a filter sounds the way it did the day it left the factory.
We do this because these instruments still sound like nothing else, and because somewhere a player is waiting to hear one come back to life.
