Muse Spark Open vs MiMo v2.6 Flash

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.

Patchbay is a three-person studio in Rotterdam dedicated to the repair and restoration of vintage synthesizers. We work on instruments that have been sitting in attics, basements, and rehearsal rooms for decades — the ones that hum when they shouldn't, lose their voice, or refuse to power on at all. Our approach is patient and detail-oriented. We trace faults through aging circuit boards, source period-correct components when possible, and treat every repair as a conversation with the person who built the instrument, and the musicians who played it before it fell silent.

We believe these machines deserve to stay in circulation rather than end up in landfill. Whether it is a Moog, a Juno, or a machine you cannot name, bring it in and we will tell you honestly what it needs.
