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 small repair studio in Rotterdam dedicated to keeping vintage synthesizers alive. We are three people — a technician, a historian, and a musician — who believe that the instruments built in the 1960s, 70s, and 80s still have decades of sound left in them, if someone is willing to care for them properly.
We work on everything from early Moogs and Arps to Roland Junos and Oberheim OB-series, handling everything from dead power supplies and leaky batteries to full recaps and voice board restoration. Our workshop is small by design. We take on a limited number of instruments at a time, which means every synth that comes through our door gets our full attention.
Most of our clients are working musicians, collectors, and small studios across Europe, but we also welcome instruments with stories we'd love to hear. If you have a piece of synth history that needs care, we'd be glad to talk.
