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 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.

Patchbay is three people and one workshop in Rotterdam, and we spend our days bringing old synthesizers back to life. Most of what arrives at our bench is somewhere between thirty and fifty years old: a Juno with a dead voice chip, a Minimoog that drifts out of tune the moment the room warms up, a Polysix whose battery has quietly eaten its own circuit board. We know these instruments inside and out because we have had hundreds of them open on the table.

We started Patchbay because we kept meeting musicians who had been told their synth was not worth fixing. We disagree. These machines were built to be serviced, and with the right parts, enough patience, and a good set of schematics, almost any of them can be made to play again. When we hand an instrument back, we want it to sound the way it did the day it left the factory, or better.
