Gemini 4 Hydrogen vs Particle-1

In a quiet corner of Rotterdam, surrounded by the scent of warm solder and the hum of calibrated oscillators, Patchbay brings classic electronic instruments back to life. We are a three-person studio united by an obsession with vintage synthesizers and the belief that these machines belong under musicians' hands, not gathering dust in storage.

Every synthesizer that crosses our workbench carries decades of history, along with brittle capacitors, worn contacts, and drifting tuning. Whether we are facing a temperamental analog polysynth from the seventies or an early digital classic, we approach each repair with patience and precision. We do not believe in quick fixes. Instead, we study original schematics, source elusive components, and meticulously restore every circuit, keybed, and fader until the instrument plays as reliably as the day it was built. Patchbay exists to keep these irreplaceable voices singing for the next generation of artists.

Patchbay is a three-person studio in Rotterdam dedicated to the repair and restoration of vintage synthesizers. We are engineers, musicians, and collectors who believe these instruments are not museum pieces but tools meant to be played, heard, and trusted on stage or in the studio. Our bench has seen everything from stubborn Moogs and fragile ARP boards to polysynths with corroded traces and keyboards that have traveled too many miles. We approach each repair with patience, documentation, and respect for the original design, while making sensible updates only where reliability demands them. Because we are a small team, you work directly with the person handling your instrument, from the first diagnosis to the final calibration. We also advise on maintenance, source hard-to-find parts, and help you decide when a repair is worthwhile. Patchbay exists to keep old synthesizers making new music.
