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 repairing vintage synthesizers. We work carefully, one instrument at a time, because old machines deserve patience. Our bench is crowded with test leads, spare knobs, tired capacitors, and service manuals held together by tape. Every repair begins with listening. We power up the synth, play a few notes, and trace the fault by ear before opening the case. Perhaps the filter drifts as it warms. Maybe a voice cuts out, or the envelope behaves strangely. We clean contacts, replace components only when necessary, and keep original parts wherever possible. We believe repair is a form of preservation. These instruments were built to be played for decades, not replaced when something small fails. Rotterdam has a long history of making and fixing things, and we are proud to continue that tradition. Bring us your beloved keyboard, and we will see what can be saved.

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.
