The Leatherwood Amber Range Double Bass Rosin
The LEATHERWOOD ROSIN folks have come up with a wide range of bass rosins for the contrabass that is formulated for a range of playing from solo and chamber music in a hot climate to heavy orchestral playing in cold, dry weather. Among the formulations, there are some formulated explicitly for playing on gut strings.
The LEATHERWOOD rosins are discussed in terms of five criteria that are important for players:
Grip - The strength of 'stickiness' at the beginning of the note
Traction - The power of the 'stickiness' for sustained bowing
Lyrical Quality - How well the rosin performs for singing quality, particularly in higher registers.
Powder content - How much powder resin is included
Pliability - How soft and malleable the rosin is in your hand
The formulations range from Hard/crisp - 20% to Soft/sticky - 60%. The best range for gut strings is in the 40% to 50% range, and to give players the best experience, we include two formulations in each package; one 40% cake and one 50% cake. Using the above criteria, these two formulations are different in the following ways:
Grip - The 50% formula has slightly better grip than the 40%, which is somewhat harder.
Traction - The 40% formula has slightly better traction than the 50%.
Lyrical Quality - The 40% formula has a slightly better lyrical quality than the 50%.
Powder content - The 40% and 50% have about the same powder content.
Pliability - The 50% formula has more pliability than the 40% formula.
You can achieve the perfect bowing properties by mixing the two formulas on your bow.
