Glimpse vs Muse Spark Open

Patchbay is a small repair studio in Rotterdam, built around three hands, one bench, and a shared patience for machines that should have been forgotten. We work on vintage synthesizers — the hissing, glowing, drifting instruments that shaped records decades ago and still find their way to us in boxes, corners, and half-finished projects. Some arrive dead silent. Others howl through cracked pots, sticky keys, and memories of bad rooms. We like that. Our approach is careful: diagnose, restore, and explain what we found. We replace what must be replaced, but we preserve what gives an instrument its character, including its quirks when they are honest ones. Each repair is handled directly by the three of us, from first inspection to final listening. We are not a factory and we do not rush. We are three people in Rotterdam who believe old synthesizers deserve attention, patience, and a little stubborn love.

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.
