About Human Error Synth Repair
With a background in music and electronic media, after more than 20 years I eventually ended up in a modest workshop in Rotterdam, where almost every (work)day I get to tinker with the most wonderful instruments and projects – and I love every minute of it.
If you ask me, there is far too much junk around us, and I don’t get the impression it’s getting any less. That bothers me enormously, and it’s genuinely one of the reasons I do this work. There was a time when manufacturers took much more pride in building things to last, but I believe we can still make a difference today.
On top of that, musical instruments and studio equipment are the tools artists and producers use to tell their stories. For me, repairing them is also a way of preserving those stories.
At the same time, I see instruments being thrown away or pushed aside for no good reason. That’s a shame, both for our culture and for the environment. That’s why I’m committed to repair and restoration. Not only because it’s technically challenging, but also because it (hopefully) contributes to a more sustainable future.


There’s already far too much cheap stuff
The electronic music industry suffers from the same throwaway mentality that plagues technology worldwide: many devices get replaced rather than repaired. This leads to huge amounts of electronic waste (e-waste), with harmful consequences for the environment.
Repairing equipment not only extends its lifespan, it also avoids the unnecessary production of new materials. With in-depth technical knowledge, I tackle problems that others sometimes consider unsolvable. Also read what I think of Behringer.
Whenever I can, I also try to support open source projects. Partly through things like a discount on labour, but also by actively contributing to design, documentation and testing.
Synthesizers are (also) cultural heritage
Synthesizers are more than just hardware; they are part of music history. Every instrument carries a unique design and sonic character, shaped by the technology and creativity of its time. Some instruments drive entire genres; others are forgotten for years, only to suddenly resurface out of nowhere.
Preserving these instruments is therefore also a way of conserving cultural heritage. By restoring them, I make sure these iconic sounds and possibilities remain available to future generations, and help keep a musical tradition alive.

Please take good care of your gear
Good repair work doesn’t stop at replacing parts. Preventive maintenance and timely care are crucial to keeping an instrument working at its best. Regular check-ups and specialist care prevent breakdowns and preserve playability.
My approach is always tailored. Every system is unique and calls for specific knowledge, experience and attention. That’s the only way an instrument stays true to its character and technically healthy.
Who I help
My clients range from professional studios and producers to collectors, musicians and hobbyists who cherish their instruments. From my modest workshop on the Coolhaven in Rotterdam, I welcome synth nerds, techno freaks, modular geeks, pianists and bassists, composers, guitarists, solder junkies, gabbers, Kraftwerk cover bands and audiophiles of all shapes and sizes. If you’re in the neighbourhood, feel free to drop by for a chat and a cup of coffee!

Recommendations
People often ask me where to find good accessories or practical gear that genuinely add something.
Here are a few things I’m personally enthusiastic about:
Dust covers – Iwan op Maat
Handmade covers, made to measure for your synth. Ideal for keeping your instrument dust-free after an overhaul – and they look great too. He also makes beautiful furniture for your instruments.
