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 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.
