Patchbay is a three-person studio in Rotterdam dedicated to bringing vintage synthesizers back to life. We repair analog and digital instruments that shaped the sound of music, from classic drum machines and polyphonic synths to quirky, characterful machines that rarely leave a musician’s side. Our work combines technical knowledge with respect for each instrument’s history, because a synth is more than a circuit board: it carries the decisions, compromises, and personality of its original design. We diagnose faults, restore unreliable voices, and carefully service aging components without erasing the character that made an instrument worth keeping. Whether a machine has been silent for years or simply needs a thoughtful tune-up, we treat every repair as a careful act of restoration. Based in Rotterdam, Patchbay works with musicians, studios, collectors, and anyone who believes electronic instruments deserve another chapter. We restore them to sound as they should, preserving the details that make each one unique.

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 a three-person studio in Rotterdam devoted to repairing vintage synthesizers and keeping electronic instruments alive. We work with analog and digital keyboards, drum machines, and modular systems, restoring worn circuits, replacing fragile components, and returning each machine to reliable musical use. Our small team combines careful technical work with genuine respect for the instruments that shaped decades of music. Whether an instrument needs a routine service, a difficult diagnosis, or a full restoration, we approach it with patience, clear communication, and attention to detail. We believe these machines are not just equipment; they are tools with history, character, and sound worth preserving. Based in Rotterdam, we serve musicians, collectors, and studios who want their gear maintained properly and played again. At Patchbay, every repair is treated as a collaboration between craft and music, ensuring that classic synthesizers continue to inspire new sounds for years to come.

Patchbay is a three-person repair studio in Rotterdam, tucked between a bike shop and a coffee roastery, where vintage synthesizers come to live another life. We are not a factory and we are not a museum; we are technicians who love the smell of warm solder and the patience that old circuits demand. Between us we have restored everything from early Moog modulars to battered Junos, and we treat each instrument as if it were the first one we ever opened. There is no assembly line here. Every capacitor is tested, every busbar tracked by hand, and every voice board is listened to twice—once on the bench, once through the speakers of the synth that will use it. Patchbay exists because these machines deserve more than a quick fix. They deserve someone who knows their quirks, their failures, and the strange, beautiful sounds that made us fall in love with them in the first place.

Patchbay is a small studio in Rotterdam where vintage synthesizers come back to life. We are three technicians, musicians and longtime collectors who have spent the last decade trading schematics, hunting spare parts, and learning the quirks of every oscillator and filter that has passed through our hands. What started as helping friends keep their Junos and ARPs in tune has grown into a dedicated workshop in the north of the city. We repair, restore and service instruments from the sixties to the early nineties, from well-known classics to rare prototypes that barely left the factory. We believe these machines are more than equipment. They carry histories, imperfections and sounds that cannot be replaced. Our job is to respect that character while making sure each instrument is reliable, playable, and ready for another lifetime of music.

Patchbay is a three-person studio in Rotterdam dedicated to bringing vintage synthesizers back to life. We started with a shared obsession for the circuits, keyboards, and sonic quirks of the instruments that shaped electronic music, and we turned that obsession into a careful, hands-on repair practice. Every synth that comes through our door is treated as its own project—diagnosed by ear, opened with care, and restored using a mix of original components and thoughtful modern solutions where needed. We work with collectors, studios, and musicians who value the character of older gear and want it to keep sounding its best. Based in Rotterdam, we combine technical precision with a deep respect for the history inside every chassis. At Patchbay, repairing isn’t just about getting a machine working again; it’s about preserving the voice of an instrument and keeping it ready for the next recording, performance, or moment of inspiration.

In a quiet industrial building overlooking the Maas, the air smells of warm dust, solder flux, and ozone. This is Patchbay, a three-person workshop in Rotterdam dedicated to keeping the golden age of electronic music alive. We don’t view vintage synthesizers as museum pieces to be locked behind glass. To us, a Roland Jupiter-8 or an ARP Odyssey is a living, breathing instrument meant to be played, gigged, and pushed to its sonic limits. Between the three of us, we have spent decades deciphering faded schematics, hunting down obsolete transistors, and cleaning decades of club grime from beneath weighted keys. Rotterdam is a city built on raw electronics and relentless rhythms, and we take pride in keeping its hardware running. Whether you bring us a touring workhorse with a dead voice chip or a garage-find modular rig that hasn’t powered on since 1984, we are here to make it sing again.

Patchbay is a three-person workshop based in Rotterdam, dedicated to keeping vintage synthesizers alive and playable. We are technicians, musicians, and obsessive tinkerers who believe that classic analog instruments deserve better than silence. From temperamental Jupiter-8s to worn-out ARP Odysseys, we restore, repair, and maintain the machines that shaped the sound of modern music. Every repair starts with listening—both to the instrument and to the person who plays it. Whether you are chasing a rare fault, need a full calibration, or simply want your old synth to feel new again, our bench is open. We understand that no two synthesizers arrive with the same story, and we treat each circuit, slider, and key with the care its history deserves. At Patchbay, we are here to make sure the sounds of tomorrow are built on those that came before.

Patchbay is a three-person studio in Rotterdam, and we spend our days inside vintage synthesizers. We are repair technicians first: we open the cases, replace the leaking capacitors, re-tune the oscillators that have drifted out of pitch, and bring back the filters that went silent decades ago. Our bench is crowded with service manuals, spare chips, and a soldering station that has seen more Moog panels than we can count. We started the studio because we kept meeting musicians whose favourite instruments sat unused in cupboards, not because they were broken beyond saving but because nobody nearby knew how to fix them. We still believe most of these machines can be made to sing again, and we would rather spend an afternoon finding the one bad resistor than see another good synth end up in a skip.

Patchbay sits in a former warehouse on Rotterdam's northern edge, where the Maas meets the industrial harbour. Three of us work here—no more, no less—surrounded by oscilloscopes, desoldering stations, and the persistent hum of transformers. We repair vintage synthesizers. That is the whole business. We are not a museum, and we are not a factory. Every Minimoog, ARP 2600, or Juno that crosses our bench receives the same stubborn attention: traced schematics, replaced capacitors, calibrated voltages, hours spent listening for the note that was never quite right. The machines arrive broken, silent, forgotten. They leave singing. Rotterdam built its reputation on moving heavy things and keeping them moving. We apply the same pragmatism to circuits that predate us by forty years. If it made sound once, it can make sound again. That is the promise we keep, solder joint by solder joint.

Patchbay is a three-person studio tucked into a quiet corner of Rotterdam, dedicated to repairing vintage synthesizers. We work on instruments from the seventies and eighties—Moog, Roland, Sequential, ARP—and everything in between, from stubborn oscillator drift to full restorations of boards untouched for decades. Each synth that crosses our bench has a history, and we treat it like one. We trace circuits, replace capacitors, clean contacts, and recalibrate pitch with patience rather than shortcuts, because these machines deserve better than quick fixes. Beyond repairs, we help musicians find the right instrument, advise on maintenance, and occasionally rescue projects others have given up on. We are three people, one shared workbench, and a wall of drawers filled with obsolete parts we refuse to throw away. If your synthesizer has stopped singing, bring it by. We'll listen to what it's telling us, and we'll get it back in tune.

Patchbay is a three-person repair studio in Rotterdam dedicated to keeping vintage synthesizers alive. We work on analog instruments from the seventies and eighties — the Junos, the Prophets, the Jupiter-8s — machines that were built to last but still need care after decades of use. Our workshop is small by design. Every synth that comes through the door gets diagnosed, serviced, and calibrated by hand, with attention to the original components wherever possible. We believe these instruments have a character that modern replicas can't fully capture, and our job is to preserve that. Whether it's a failing voice chip, a cracked potentiometer, or a full recap, we approach each repair with the same respect for the instrument's history. We're not a factory or a resale operation. We're three people who love this gear and want to see it played for another thirty years.

Patchbay is a three-person repair studio in Rotterdam devoted to keeping vintage synthesizers alive. We work from a small workshop in the north of the city, where every bench is crowded with oscillators, filters, and half-finished patch cables. Our days are spent tracing faulty circuits, recapping power supplies, and coaxing tired keyboards back to full voice. We started Patchbay because we love these instruments and the music they still have to make. A Jupiter, a Juno, an MS-20, a modular wall built from spare parts — each one has a history, and each one deserves careful, patient repair rather than replacement. We service classics from the seventies and eighties, source rare components, and calibrate every machine by ear as well as by meter. We are musicians, technicians, and collectors ourselves. When you bring us your synth, we listen to how you use it, explain what we find, and return it ready to play for years to come.

Patchbay is a three-person repair workshop in Rotterdam. We fix vintage synthesizers — the analogue ones first, then the digital oddities that turn up in equal measure. Oscillators that have gone flat, voice cards that need recapping, keybeds whose contacts have oxidised, encoders that no longer click where they should. Work that other people have given up on tends to end up on our bench. We got into this because none of us could afford to be the person who threw away a Juno-106 over a bad multiplexer chip. So we learned to solder, learned to read service manuals, learned to source parts that stopped being manufactured decades ago. The three of us divide the work between us, and we each handle bench repairs, diagnosis, and the endless sourcing and cleaning that any restoration actually requires. If you have a synth that sounds wrong, smells hot, or simply stopped making noise, get in touch. We will tell you honestly whether it is worth fixing.

Patchbay is a three-person studio in Rotterdam, keeping vintage synthesizers in working hands. We repair the instruments that have picked up a crackle, lost a voice, drifted out of tune, or stopped making sound altogether. We like the patient side of repair: tracing a fault, understanding an old circuit, and finding the right fix rather than the quickest workaround. Our aim is to make each instrument dependable without sanding away the character that made someone fall for it in the first place. Some synths arrive with a clear problem. Others come with a story and a noise that only happens after twenty minutes. Either way, the work starts with listening—to the instrument and to the person who plays it. We’re a small studio by choice. It keeps us close to the work, and to the musicians who trust us with something they want to keep making music with.

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 three people in a narrow workshop near the Maas in Rotterdam. Every day we open up instruments that were built before most of their current owners were born. Some arrive in flight cases and some come wrapped in old bath towels. Most have a story: a Juno that went quiet halfway through a gig, a Minimoog left in someone's attic for thirty years, or a modular system that a previous technician gave up on. We started Patchbay because we kept seeing good synthesizers sent off as "unrepairable" when all they needed was patience, a schematic and a steady hand. We swap out dried capacitors, hunt for intermittent faults, recalibrate oscillators until they track properly again, and source or rebuild parts that stopped being made decades ago. We don't try to make old machines sound new. Our job is to make them sound like themselves again, and to make sure they keep working for the next person who plays them.

Patchbay is a three-person studio in Rotterdam devoted to repairing vintage synthesizers. We work with instruments that have been played, carried, opened up, and passed from one owner to the next. Each arrives with its own history and its own set of quirks, so we begin by listening carefully and tracing the problem before reaching for a fix. Our work ranges from straightforward maintenance to deeper electronic repairs. We clean, test, diagnose, and restore with the aim of making a synthesizer reliable again while respecting the design that gives it its voice. When a repair calls for a replacement part, we look for a solution that fits the instrument rather than treating it as disposable. Patchbay is run by three people who share a curiosity about how these machines work and a respect for the sounds they make. We believe a well-cared-for synthesizer has plenty more music in it, and we’re here to help it find its way back into someone’s hands.

Patchbay is a three-person studio in Rotterdam dedicated to repairing vintage synthesizers. We work on instruments that have shaped decades of music, from early analog monosynths to the polyphonic machines of the eighties, bringing them back to the condition their makers intended. Every repair begins with a careful diagnosis: we trace faults through schematics, test components by hand, and replace only what truly needs replacing, preserving original parts wherever we can. Beyond fixing faults, we service worn keybeds, recalibrate oscillators, clean contacts, and restore tired power supplies, so that each instrument leaves our bench reliable and ready to play. We believe these machines deserve to keep making music rather than gather dust, and that careful, patient work is the best way to honour them. Whether you rely on your synthesizer nightly or cherish it occasionally, we treat it with the same respect and attention.

Patchbay is three people, one workbench, and a room in Rotterdam full of machines waiting to sing again. We met in a repair queue, argued about capacitor brands, and never quite stopped. Between us we hold about forty years of solder smoke: poly synths with dead voice boards, tape echoes turned to tar, modular systems grown quiet behind their patch points. We work slowly and in the open. Every fault is traced before a single part is ordered, every change is written down, and nothing leaves the studio sounding less like itself than when it arrived. Restoring a vintage synthesizer is not nostalgia. It is keeping a specific instrument, with a specific voice, in the hands of the people who play it. If yours is one of them, bring it in. We will tell you honestly what it needs, what it costs, and how long it will take.

Patchbay is a three-person workshop in Rotterdam, tucked into an old warehouse where the light is good and the benches are always covered in parts. We repair vintage synthesizers — the analog giants, the odd Japanese curiosities, the machines that were built to last and mostly have. Between us we've spent decades tracing dead oscillators, recapping power supplies, and coaxing behaviour back out of circuits that other people had given up on. We work slowly, because these instruments reward patience, and we test everything by ear as well as by meter. Some arrive barely alive; some just need one stubborn voice brought back into tune. Either way, we treat each one as a piece of history worth keeping in use. If it makes sound, we'd like to hear it again.

Patchbay is three people and one workshop in Rotterdam, and we spend our days bringing old synthesizers back to life. Most of what arrives at our bench is somewhere between thirty and fifty years old: a Juno with a dead voice chip, a Minimoog that drifts out of tune the moment the room warms up, a Polysix whose battery has quietly eaten its own circuit board. We know these instruments inside and out because we have had hundreds of them open on the table. We started Patchbay because we kept meeting musicians who had been told their synth was not worth fixing. We disagree. These machines were built to be serviced, and with the right parts, enough patience, and a good set of schematics, almost any of them can be made to play again. When we hand an instrument back, we want it to sound the way it did the day it left the factory, or better.

Patchbay is a three-person studio in Rotterdam devoted to the restoration and repair of vintage synthesizers. We believe analog gear holds a living voice, and our purpose is to safeguard that sound for musicians, collectors, and creators who value authenticity. With hands-on experience in circuitry, voltage calibration, and component preservation, we treat every console, drum machine, or modular voice with meticulous care. Rotterdam’s eclectic artistic community fuels our commitment to keeping analog heritage alive, bridging past technology with present music. Whether rescuing a neglected lab unit or reviving a cherished polysynth, we approach each instrument as a unique piece of musical history, ensuring it performs as intended for years ahead. We love helping artists reconnect with the warmth and character only vintage hardware can offer. Our workshop sits in the heart of the city, where dusty circuit boards meet fresh compositions, and every repaired synth becomes part of a new musical story.

Patchbay is a small workshop tucked away in the heart of Rotterdam, where three friends have been breathing new life into vintage synthesizers since 2018. Each of us brings a different background to the bench: one spent years restoring Moog and ARP instruments in a London studio, another cut his teeth on modular systems in Berlin's electronic music scene, and the third holds a degree in electrical engineering focused on analog circuit design. Together we've repaired everything from sun-faded Korgs to temperamental Oberheims, always with the same goal in mind: returning each instrument to the hands of the musicians who need it, rather than letting it collect dust on a shelf. We believe every synthesizer has a voice worth preserving, and that the warmth of analog sound is more than voltage — it's memory, texture, and story. At Patchbay, we don't just fix machines; we keep the music alive.

Patchbay is a three-person studio in Rotterdam dedicated to repairing and restoring vintage synthesizers. Founded by electronic musicians who grew frustrated watching beloved instruments fall silent, we approach each repair with the reverence these machines deserve — not as collectibles, but as living tools for sound. Our bench has revived everything from corroded Minimoogs and temperamental Jupiter-8s to obscure European modular systems and forgotten Japanese curiosities. We source original components where possible, fabricate what no longer exists, and document every intervention so the next technician inherits clarity, not guesswork. Beyond repair, we consult on studio integration, design custom modifications, and run a small workshop series teaching synthesis fundamentals through hands-on restoration. We also collaborate with conservatories and museums on preservation projects, ensuring institutional knowledge doesn't vanish with the generation that built these instruments. The goal is simple: keep the instruments playing, and keep the knowledge circulating.

Patchbay began in a cluttered apartment in Rotterdam, where three friends spent weekends coaxing old synthesizers back to life. What started as a shared obsession quickly outgrew the living room. In 2016, we opened our first proper workshop in a converted warehouse on the south side of the city, and we have been soldering, calibrating, and listening closely ever since. We are a small team of three. Niels handles the analog work, coaxing warm tones from aging oscillators and reluctant filters. Marijn focuses on digital systems and the occasional stubborn MIDI quirk. Sanna manages restorations, sourcing rare components and keeping long projects on track. Between us, we have decades of experience with the machines that shaped electronic music. Every synth that passes through our doors carries decades of sound inside it. Our job is to make sure that story continues.
