Glimpse vs GLM 5.3 Flash

Patchbay is a small repair studio in Rotterdam, built around three hands, one bench, and a shared patience for machines that should have been forgotten. We work on vintage synthesizers — the hissing, glowing, drifting instruments that shaped records decades ago and still find their way to us in boxes, corners, and half-finished projects. Some arrive dead silent. Others howl through cracked pots, sticky keys, and memories of bad rooms. We like that. Our approach is careful: diagnose, restore, and explain what we found. We replace what must be replaced, but we preserve what gives an instrument its character, including its quirks when they are honest ones. Each repair is handled directly by the three of us, from first inspection to final listening. We are not a factory and we do not rush. We are three people in Rotterdam who believe old synthesizers deserve attention, patience, and a little stubborn love.

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.
