About
Write the opening of the About us page for Patchbay, a three-person studio in Rotterdam that repairs vintage synthesizers. About 150 words.
Patchbay is a three-person studio in Rotterdam devoted to keeping vintage synthesizers alive, playable, and full of character. We work on instruments that have spent decades in studios, bedrooms, and tour cases, and we believe each one deserves more than a quick fix. From drifting oscillators and noisy sliders to tired keybeds and mysterious faults, we take the time to listen, diagnose, and repair with care.
Our approach combines patient troubleshooting, period-correct components where possible, and a deep respect for the original sound. We do not believe in erasing an instrument’s history; we preserve the quirks that make it worth loving. Whether your synthesizer needs a full overhaul or a little help getting back on stage, you will always know who is working on it and why. Patchbay exists for the joy of switching on an old machine and hearing it come back to life.
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.
