Patchbay is a three-person studio in Rotterdam dedicated to the repair and restoration of vintage synthesizers. The name comes from the heart of every modular system: the point where all the signals meet. We work on the machines that shaped the sound of the last fifty years—Junos, Prophets, Minimoogs, and the strange, wonderful instruments that never made it into the history books. Our workshop is a place of solder smoke and oscilloscope traces, where dead oscillators are coaxed back to life and tired potentiometers are quietly replaced with period-correct parts. We believe these instruments deserve to stay alive: not as museum pieces, but as working tools for the musicians, producers, and studios who play them every day. Between the three of us, we bring decades of experience in electronics and restoration, and a stubborn refusal to let good machines go to waste.
