Because there are 60 students in every class room in the school where the sister teach, they were told to use microphone and amplifier during class. This is for the students to hear what the teacher is saying, also for the students to take part during music class. The sister been using the old amplifier that the brother assembled years ago and it does work well anymore. Because of this reason the sister decided to buy the excellent fishman loudbox at musicians friend. This is so perfect for the sister’s classroom and the sound is nice as well. Teaching music would be more fun for the sister using this amplifier I must say. The sister can use this amp when there is program at their class like Christmas party. Also, the sister can listen to her favorite songs while during the lesson plan, making grades, checking papers, and the likes when the classes ends in the afternoon.
