D’Addario Kaplan Premium Rosin gives a warmer, richer tone and I love the way it sounds!

when I began to play it had a wonderful rich tone that I don't think my cello has ever produced

The tone is more sweet and less sratchy than Goldflex, as well.

Besides producing a nice tone, it is easy to use.

The rosin promotes a better tone quality than the last brand we used and we are very happy with this purchase

This is really disappointing, but its tone is not bad, just the stone is not very good.

The rosin I was using gave my violin a scratchy tone to it, but this rosin is fantastic, and gives it a more pure, resonating sound

Right away I could tell a big difference in the amount of dust generated and a clearer tone while playing

Excellent Roisin child does not give up now because of pot squeaky sound..helps to get rich deep tone.
