In Kuala Lumpur, there are only very few Luthier that I liked and trustworthy. One of them is definitely Mr. Ong Ket Wei. I find that he is friendly and easy to be approach. Through my experienced, his workmanship is of the highest quality and this makes our life as professional musician much easier if we need to have our expensive instruments to be service and repair.
