MiMo v2.6 Flash vs GLM 5.3 Flash

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 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.
