Ling 3.2 Flash vs GLM 5.3 Flash

Patchbay is a three-person repair studio in Rotterdam, devoted to vintage synthesizers. We are two electronics technicians and one former touring musician, and between us we have spent decades around machines that hum, drift and occasionally die on stage. Our bench sits in a quiet unit just off the Maas, where we take apart oscillators, resurrect dead filter circuits, free stuck keys and give tired capacitors somewhere better to be. Some instruments arrive barely alive; others only need a careful clean, a recalibration and someone willing to listen properly. We work slowly, document everything we find, replace only what needs replacing, and protect what makes each synth sound like itself. It is quiet, exact work, and we think it matters. Every repair leaves tested, tuned and ready for another twenty years. If yours has stopped speaking, bring it by; we'd like to hear what it used to say.

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.
