About

Write the opening of the About us page for Patchbay, a three-person studio in Rotterdam that repairs vintage synthesizers. About 150 words.

In a quiet corner of Rotterdam, surrounded by the scent of warm solder and the hum of calibrated oscillators, Patchbay brings classic electronic instruments back to life. We are a three-person studio united by an obsession with vintage synthesizers and the belief that these machines belong under musicians' hands, not gathering dust in storage.

Every synthesizer that crosses our workbench carries decades of history, along with brittle capacitors, worn contacts, and drifting tuning. Whether we are facing a temperamental analog polysynth from the seventies or an early digital classic, we approach each repair with patience and precision. We do not believe in quick fixes. Instead, we study original schematics, source elusive components, and meticulously restore every circuit, keybed, and fader until the instrument plays as reliably as the day it was built. Patchbay exists to keep these irreplaceable voices singing for the next generation of artists.

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.
