Steps to the establishment of our company

When I was involved in the manufacture and repair of custom guitars at a musical instrument retail store where I got a job, the world was in the bubble era. At that time, the sales volume of musical instruments was more than solid, and repairs were more frequent, and I remember doing so many nuts and frets every day that my arms were paralyzed. And it was a stoic day where I stayed up all night for many days until I was satisfied with the result, and devoted myself to it from beginning to end regardless of my hobbies or money.

After a while, I left the company and founded our company after working as a private maker. After that, I also designed / designed guitars made by manufacturers and developed pickups. Fortunately, I met some of the most respected musicians / artists, and I've done a lot of guitar repairs and setups for them. And I received a lot of experience and wisdom from those people.

Naturally, I have the technology ... I am thinking about how much communication ability is required for this work. The customer may be hurt by the broken instrument ... As a worker, it is easy to forget in the work that spreads such feelings. We, Infinity employees, try to set up a place for discussions about trivial matters such as this for our customers as we proceed with the work. Also, if you look at the guitar that has been played with many years of skill (Repairman's special ability?), You will be able to understand how to play and how to use it. There are hints on how to make it sound better and how to make it harder to break. When requesting repairs, please ask us even if it is a trivial matter.
