Kolstein’s Formulation Supreme Bass Rosin is composed of the finest ingredients, created through a high degree of product control in strict accord with the developed formula. A minimum curing period for a predetermined time is a requirement for all our bass rosin. In addition, such features as hand pouring and packaging in a specially designed roll-down silicon unique containerization , all contribute to the superior quality of our rich dark textured rosin.

The rosin is available in a deluxe line which consists of a protective silicon packaging  that affords the bassist a rosin packaging that keep the bass rosin fresh,  and prevents any kind of melting out of older packaging. The silicon rosin housing then is put in an attractive gold foil container; esthetic and protective for the professionals’ needs, but practically sized with easy storage in mind. Our Formulation Supreme Bass Rosin can be acquired in several grades (Hard, All Weather, amd Soft) to meet the musicians’ personal preference, as well as the geographic and climatic conditions that prevail where the rosin will be used.

As with all Kolstein Formulation Supreme Rosins, our bass rosins have the feature of indefinite shelf-life; that is, it will never dry out and crystallize. Once used, the rosin will show a continual wetting action allowing for easy powdering on the strings and instrument.

Through extensive research and experimentation, Kolstein Bass Rosin has attained this unique and revolutionary Formulation Supreme. The result is bass rosin which has been fully acclaimed by our finest international soloist and ultra-professional orchestral and recording artists.
