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 dedicated to bringing vintage synthesizers back to life. We started with a shared obsession for the circuits, keyboards, and sonic quirks of the instruments that shaped electronic music, and we turned that obsession into a careful, hands-on repair practice. Every synth that comes through our door is treated as its own project—diagnosed by ear, opened with care, and restored using a mix of original components and thoughtful modern solutions where needed. We work with collectors, studios, and musicians who value the character of older gear and want it to keep sounding its best. Based in Rotterdam, we combine technical precision with a deep respect for the history inside every chassis. At Patchbay, repairing isn’t just about getting a machine working again; it’s about preserving the voice of an instrument and keeping it ready for the next recording, performance, or moment of inspiration.
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.
