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 small workshop in Rotterdam where old synthesizers come back to life. We are three people — a former recording engineer, a self-taught circuit obsessive, and a classically trained pianist who fell in love with broken machines — and between us we have spent decades coaxing sound out of equipment the rest of the world gave up on.

We started Patchbay because we kept meeting the same problem: beloved instruments sitting silent in attics and studio corners, written off as unfixable. A Juno with a dead voice chip. A Prophet that drifts out of tune. A Moog that hums when it shouldn't. To us, none of these are lost causes. They are instruments with history in them, and they deserve careful hands, original parts where possible, and honest work.

Every synth that leaves our bench is played, tested, and listened to — because that is what it was made for.
