Muse Wonder vs GLM 5.3 Flash

Patchbay is a small workshop in Rotterdam where three of us spend our days bringing vintage synthesizers back to life. We repair and restore instruments from the 1960s, 70s, and 80s — Minimoogs with drifting oscillators, Junos with silent choruses, Prophet-5s that have not powered on in decades — tracing faults board by board, replacing tired components, and calibrating each machine until it sounds musical again. We believe these instruments were built to be played, not preserved behind glass, so we work carefully and reversibly wherever possible, documenting every repair and keeping original parts when they can be saved. Musicians, studios, and collectors bring us synths from across Europe, sometimes in flight cases, sometimes in pieces. Whether it needs a full restoration or a single sticky key, we treat it as if it were our own, and we will not send it home until we would happily play it ourselves.

Patchbay began the way most repair shops do: with a broken synth, a stubborn owner, and a soldering iron that refused to stay idle. We're three people—Joris, Marit, and Tomas—working out of a small workshop on the back streets of Rotterdam-Noord, surrounded by oscilloscopes, spare parts, and instruments that sometimes arrive in worse condition than their owners admit.

Between us, we've spent decades repairing and restoring vintage synthesizers: Rolands, Moogs, Korgs, Yamahas, and machines whose manuals were never written in the first place. We don't sell anything. We fix things. That focus keeps us honest and keeps the work slow, careful, and done properly.

We believe old instruments deserve to keep making music, not gather dust in attics or fetch prices only collectors can pay. Whether it's a cracked keybed, a dying power supply, or a voice that's gone quiet, we'd like to help bring it back.
