Wood ba siya? Or steel? Tight mo pero lagyan mo ng muffling.kasi naturally mag kakaovertone
Siya pag mahigpit.so control it with muffling na lang lalo na pag steel.pero don't kill the overtone
And one more thing pantayin mo tension bawat lug,keeping a same pitch on each lug,
It would make the sound buo.and lessens the overtone as well.
