About
Write the opening of the About us page for Patchbay, a three-person studio in Rotterdam that repairs vintage synthesizers. About 150 words.
Patchbay is a three-person studio in Rotterdam dedicated to repairing vintage synthesizers. We work on the instruments that have shaped decades of music, from well-loved studio staples to curious machines that have spent years in storage.
Old synthesizers develop problems in their own ways. A key stops responding, a filter drifts, a power supply gives out. We take the time to trace the fault, understand the instrument and make a repair that respects how it was built. Wherever possible, we preserve original components; when a part needs replacing, we choose with care.
We know these instruments are more than collections of circuits. They carry sounds, habits and memories, and each one has a story before it reaches our bench. Whether you rely on yours every day or are hoping to hear it again after a long silence, our aim is to help you get back to making music.
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.
