DeepSeek V4.1 Flash 1017 vs Claude Sonnet 5.5

Patchbay is a three-person studio in Rotterdam devoted to keeping vintage synthesizers making the sounds they were built to make. We repair, service and restore analog instruments from the late 1960s onward, from familiar Moogs and ARPs to oddities with no service manual. Every synth that comes through the door is treated as a working instrument rather than a museum piece. We trace faults, rebuild power supplies, refresh capacitors, clean keybeds and calibrate oscillators, always with an eye on reliability and the character that made the machine worth saving. We document what we do, explain the options clearly and never replace more than necessary. Whether you need one dead voice brought back or a full restoration, we work carefully, at the bench and in conversation with you. Old synths belong on records and stages, and our job is to keep them there.

Patchbay is three people in a workshop in Rotterdam, trying to keep old synthesizers alive. We repair, restore and recalibrate the instruments that shaped electronic music: Moogs and Oberheims, Rolands and Sequential Circuits, the odd temperamental Soviet oddity that someone found in an attic.

Most of what lands on our benches has been silent for years. A crackling pot, a drifting oscillator, a power supply that gave up in 1994. Some come from working musicians who need their instrument back before the next tour. Others come from people who inherited a dusty box from a parent and want to hear what it sounds like.

We work slowly and by hand. We trace faults with a scope and a schematic, source or rebuild parts when originals are gone, and change as little as we can. Every synth leaves with a note describing exactly what we did, so the next person to open it knows where we have been.

Come by, bring your synth, and stay for coffee.
