Leatherwood BASS has a powerful, sticky attack, with a large and broad tone, yet it retains the same smoothness and ease of use of the Amber Range. BASS offers great reliability and durability in heavy orchestral playing. If you're looking for a rosin with those characteristics, then this is something for you. BASS is the reliable, heavy duty rosin for everyday use.
BASS and BASS EXTRA are optimised to work best in tempeature controlled concert halls and studios. The ideal temperature range is 18-23 degrees Celsius.
In warmer weather, above 24 degrees Celsius, these rosins start to become softer and lose grip, which can result on a waxy feel on the bow hair. For outdoor concerts in warm weather they may not be ideal.
In colder weather, both BASS and BASS EXTRA will perform well, but will feel harder in the hand. In very cold and dry conditions, BASS EXTRA will perform better as a strong orchestral rosin.
