Claude Sonnet 5.5 vs Qwen3.8 Max (0902)

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.

Patchbay is a small repair studio in Rotterdam dedicated to vintage synthesizers. We are three people who care about old instruments, their history, and the players who keep them alive. From classic analog polys to rare drum machines, we take the time to understand each machine before we touch it. Our work is practical and respectful: careful diagnosis, honest advice, and repairs that preserve the character of the instrument. We know these synths are more than circuits and knobs. They carry stories from studios, stages, and secondhand shops, and they deserve to be treated with patience. Whether a machine needs a simple clean, a full restoration, or help finding a hard-to-source part, we aim to make the process clear and personal from start to finish. Based in Rotterdam, we help musicians, collectors, and studios keep old synthesizers making sound for years to come. We do it with patience and respect.
