Why did you join the company?
I had always been interested in the manufacturing industry, and at the time I was between jobs, so I thought why not try finding something in that field. By chance, I found a company that manufactured guitar parts, it seemed perfect since I play guitar as well. I became more and more interested and then I just applied for the job. I had no detailed knowledge about frets. After joining the company, I learned the depth of how they’re made and became even more interested in it.
Before joining the company, I never thought about how frets are made or even gave any thought. Once I started learning about the actual manufacturing process, I realized that the many types and minute differences greatly affect the sound and playing comfort. I installed a set of frets I manufactured myself on one of my guitars. Once I played it, I could clearly feel the difference, which made this job even more interesting.
The fun and rewarding things only a guitar lover can see
The more I learn about this job the more I appreciate it. Since I am a guitarist, I feel a deep connection to the products I make, and I always think, “how can I make them better?”
One of the most memorable moments of my career so far was when I was entrusted to work alone. At first, I was learning from the senior workers and then at some point I started to make my own decisions. I felt a greater sense of responsibility for my work, and at the same time, I became more aware of myself as a craftsman.


The joy of having your fret accuracy recognized
Frets are a part that requires such fine precision that it cannot be seen by the naked eye. Even the slightest deviation is unacceptable. An error as little as a millimeter can greatly affect playability and sound quality.
Overseas guitar makers, especially world-class guitar companies like Fender and Taylor, have praised our frets, saying that the level of accuracy is amazing. They feel confident knowing how accurate and precise the height and width are of our frets. We are happy to be recognized because of our work. This makes my job even more rewarding.
Concentration and planning are required
Being good with your hands is important, but what’s even more important is the ability to concentrate and keep working on detailed tasks. Fret production requires fine adjustments, and the slightest difference can affect the final quality. Since multiple processes are required to be carried out at the same time, I think someone who can move efficiently from task to task while keeping an eye on the situation in front of them is best suited for this job.
A New Challenge–Exploring the Possibilities of Different Materials
In the future, I want to research the differences in sound depending on the material.
After re-fretting my guitars, I realized how different materials produce different sounds. I also want to investigate alternative materials and nickel-free frets, so people with metal allergies might be able to use them without any worry.
I will continue challenging myself by researching and trying out frets made of different materials to create products that offer a better or different sounds.
The passion and curiosity of our craftsmen are embedded into a small part called a fret. Those hands continue to produce these frets that support the performances of guitarists around the world today.
