ទិញទ្រ How to buy a Tro, comment choisir un Tro
"Tro Khmer" has 3 strings, "Tro Ou" and "Tro Sor" only have two strings. I don't think anyone can buy a Tro Khmer. If you are not a good Tro Khmer player, you are bound to buy a bad instrument, good sound quality is very difficult to obtain, only good instrument makers can achieve this.
