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 repairing vintage synthesizers and keeping electronic instruments alive. We work with analog and digital keyboards, drum machines, and modular systems, restoring worn circuits, replacing fragile components, and returning each machine to reliable musical use. Our small team combines careful technical work with genuine respect for the instruments that shaped decades of music. Whether an instrument needs a routine service, a difficult diagnosis, or a full restoration, we approach it with patience, clear communication, and attention to detail. We believe these machines are not just equipment; they are tools with history, character, and sound worth preserving. Based in Rotterdam, we serve musicians, collectors, and studios who want their gear maintained properly and played again. At Patchbay, every repair is treated as a collaboration between craft and music, ensuring that classic synthesizers continue to inspire new sounds for years to come.
Patchbay is three people and one workshop in Rotterdam, and we spend our days bringing old synthesizers back to life. Most of what arrives at our bench is somewhere between thirty and fifty years old: a Juno with a dead voice chip, a Minimoog that drifts out of tune the moment the room warms up, a Polysix whose battery has quietly eaten its own circuit board. We know these instruments inside and out because we have had hundreds of them open on the table.
We started Patchbay because we kept meeting musicians who had been told their synth was not worth fixing. We disagree. These machines were built to be serviced, and with the right parts, enough patience, and a good set of schematics, almost any of them can be made to play again. When we hand an instrument back, we want it to sound the way it did the day it left the factory, or better.
