Particle-1 vs Muse Spark Open

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.

Patchbay is a small studio in Rotterdam where vintage synthesizers come back to life. We are three technicians, musicians and longtime collectors who have spent the last decade trading schematics, hunting spare parts, and learning the quirks of every oscillator and filter that has passed through our hands.

What started as helping friends keep their Junos and ARPs in tune has grown into a dedicated workshop in the north of the city. We repair, restore and service instruments from the sixties to the early nineties, from well-known classics to rare prototypes that barely left the factory.

We believe these machines are more than equipment. They carry histories, imperfections and sounds that cannot be replaced. Our job is to respect that character while making sure each instrument is reliable, playable, and ready for another lifetime of music.
