The Pops Bass Bow Rosin for Double Bass was created by Len "Pops" Manno, who played double bass with the Houston Symphony for 41 years. It is made in Houston, TX where the rosin is hand-mixed in small batches for high quality control and clear purity, packaged in an ecology-proof box.
The rosin is very popular worldwide because it has unique qualities that enable the bow to really "grab" the string and make a very pleasing sound. So many of the players - particularly symphony, ensemble, and solo artists - use Pops' for this reason. The rosin is necessarily soft to produce the qualities that give the bow such a good "grab."
