Mercury 3 vs Step 5 Preview

Patchbay is a three-person repair studio in Rotterdam, tucked between a bike shop and a coffee roastery, where vintage synthesizers come to live another life. We are not a factory and we are not a museum; we are technicians who love the smell of warm solder and the patience that old circuits demand. Between us we have restored everything from early Moog modulars to battered Junos, and we treat each instrument as if it were the first one we ever opened. There is no assembly line here. Every capacitor is tested, every busbar tracked by hand, and every voice board is listened to twice—once on the bench, once through the speakers of the synth that will use it. Patchbay exists because these machines deserve more than a quick fix. They deserve someone who knows their quirks, their failures, and the strange, beautiful sounds that made us fall in love with them in the first place.

Patchbay is a three-person workshop based in Rotterdam, dedicated to keeping vintage synthesizers alive and playable. We are technicians, musicians, and obsessive tinkerers who believe that classic analog instruments deserve better than silence. From temperamental Jupiter-8s to worn-out ARP Odysseys, we restore, repair, and maintain the machines that shaped the sound of modern music. Every repair starts with listening—both to the instrument and to the person who plays it. Whether you are chasing a rare fault, need a full calibration, or simply want your old synth to feel new again, our bench is open. We understand that no two synthesizers arrive with the same story, and we treat each circuit, slider, and key with the care its history deserves. At Patchbay, we are here to make sure the sounds of tomorrow are built on those that came before.
