Product Overview

The Kolstein KR-012 Cello Rosin is crafted to provide a balanced sound from strong to weak dynamics. Its unique formulation prevents drying out or crystallization, ensuring a consistent application over time. This rosin is known for its fine grain, which helps prevent rough sounds and enhances the purity of your instrument's tone.

Setup and Preparation

1. Unpacking: The rosin body is shipped within a red plastic cover, which is encased in a gold box. Carefully remove the gold box packaging.
2. Rosin Access: The plastic cover around the rosin cake is pre-cut for easy removal. Gently peel away the plastic cover to expose the rosin surface.
3. Initial Application: For first use, it may be beneficial to lightly score the surface of the rosin with a sharp object (e.g., a knife or sandpaper) to create a fine powder, which helps the rosin adhere to new bow hair more effectively. Exercise caution if scoring.

Operating Instructions

Applying Kolstein KR-012 Cello Rosin correctly ensures optimal sound production and bow performance.

1. Bow Preparation: Ensure your bow hair is clean and free from excessive old rosin buildup.
2. Rosin Application: Hold the rosin cake firmly. Draw the bow hair across the rosin surface with light, even pressure. Apply several strokes, ensuring the entire length of the bow hair that contacts the strings is covered.
3. Even Coverage: Rotate the rosin cake slightly with each application to ensure even wear of the rosin surface.
4. Amount: The amount of rosin needed varies based on playing style, bow hair type, and environmental conditions. Start with a moderate application and adjust as necessary. Too much rosin can lead to a scratchy sound, while too little results in a weak, slippery tone.
5. Benefits: This rosin's high viscosity and strong snag resistance allow for clear, pure tones and a balanced sound across all dynamics. It is designed to minimize powder residue on strings and instruments.

Maintenance and Storage

• Storage: After use, place the rosin back into its protective cloth and then into its original gold cylindrical container. This protects the rosin from dust and physical damage.
• Longevity: Kolstein rosin is formulated to have no expiration date. It will not dry out or crystallize under normal storage conditions, unlike some traditional rosins.
• Temperature: Store the rosin in a cool, dry place, away from direct sunlight or extreme temperature fluctuations, which could soften or alter its consistency.
• Cleaning: Periodically wipe down your instrument and bow stick to remove any excess rosin dust.

Troubleshooting

• Scratchy Sound: If your instrument produces a scratchy sound, you may have applied too much rosin. Try wiping excess rosin from the bow hair with a clean, dry cloth.
• Weak or Slippery Sound: If the bow slips easily on the strings or produces a weak sound, more rosin may be needed. Apply a few more strokes to the bow hair.
• Uneven Application: Ensure you are applying rosin evenly across the entire playing length of the bow hair. Uneven application can lead to inconsistent sound.
• Rosin Dust Buildup: Regular cleaning of your instrument and bow is recommended to prevent excessive rosin dust accumulation, which can affect sound quality and instrument finish.
