PetzBass Rosin Medium
Independent shopping perspective
The Korena take
Medium-grade rosin for double bass bow hair. A general-purpose cake for players who need grip without season-specific extremes.
Strong match
Who this is for
- Double bass players needing a year-round rosin
- Students restocking a worn or cracked cake
- Rooms that swing between warm and cool
Consider the trade-offs
When to look elsewhere
- Violin, viola or cello players — bass rosin is much softer
- Players who need maximum grip in a cold hall
- Rehair or bow repair needs — this is consumable rosin only
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
Bass-specific formula
Bass rosin is far softer and stickier than violin rosin. Violin rosin will not grab the thicker strings.
Detail 03
$14.99
A cake lasts most players many months. This is routine consumable spend, not an upgrade purchase.
Detail 04
Cake form
Apply with several slow passes along the hair. Fast strokes just heat and glaze the surface.
Detail 05
Works with arco playing
Only relevant if you bow. Pizzicato-only players do not need it.
Final check
Know before you order
- 01Rosin cracks if dropped — keep it in the container or a padded case pocket
- 02No bow, cloth or applicator included
- 03In hot cars soft bass rosin can soften and lose its shape
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Can I use bass rosin on a cello bow?
It is formulated for bass and is much softer and stickier. On cello it will feel gummy and noisy. Use cello rosin instead.
02How often do I apply it?
When the bow starts slipping or the tone thins out. For regular players that is typically every few playing sessions.
03Is medium the right grade for me?
Medium is the safe default. Go softer only if you play cold rooms and need extra bite, harder if warm rooms make the bow feel sticky.
04How long does one cake last?
Months of regular playing. Most cakes are replaced because they crack or get lost rather than used up.
