Detail 01
Bass rosin
Softer and stickier than violin or cello rosin, because thick bass strings need far more friction to speak.

PetzBass Rosin Soft
Independent shopping perspective
The Korena take
Soft-grade rosin cake for double bass bow hair. A consumable every arco bassist needs; it is not for cello or violin.
Strong match
Who this is for
- Double bass players bowing regularly and burning through rosin
- Restoring grip on freshly rehaired or slipping bow hair
- Keeping a spare cake in the bass case
Consider the trade-offs
When to look elsewhere
- Pizzicato-only players who never bow
- Cello, viola, or violin bows, which need harder rosin
- Anyone in a hot, humid room wanting a firmer grade
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Soft grade
More grab and a fuller low-end pull. Also more tacky, so it picks up dust and can feel sluggish in heat.
Detail 03
Cake form
You rub the bow hair across it directly. A few strokes per session is normal; over-rosining makes a scratchy tone.
Detail 04
Consumable
It wears down and cracks over time. Most players replace a cake every year or two, sooner with heavy use.
Final check
Know before you order
- 01Rosin only — no bow, cloth, or case included
- 02Soft rosin gets sticky in heat; store it out of a hot car
- 03Dropping a cake usually shatters it, so keep the container closed
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Can I use this on a cello bow?
No. Bass rosin is much softer and stickier than cello rosin and will make a cello bow feel gummy and hard to control.
02How often should I apply it?
A few strokes before each session is typical. If the tone turns scratchy or crunchy, you are applying too much.
03Soft or hard bass rosin?
Soft gives more grip and works well in cooler, drier conditions. Hard grades hold up better in hot, humid rooms.
04Does it work on a French and German bow?
Yes. Rosin goes on the hair, so the frog style makes no difference.
