Detail 01
Four-ply yarn wrap
Wool-blend over synthetic. Softens the attack so low bars speak fully instead of clacking.

PromarkFuture Pro Discovery Series Mallets Extra Large Yarn Fpy100
Independent shopping perspective
The Korena take
Extra-large yarn mallets built for contra bass bars. For percussionists who need a soft, full attack on the lowest tone bars.
Strong match
Who this is for
- Contra bass bar and low marimba parts in ensemble
- School and community percussion sections covering low mallet parts
- Players needing a soft attack without losing note definition
Consider the trade-offs
When to look elsewhere
- Glockenspiel or xylophone work needing hard articulation
- Drum set players — these are not drumsticks
- Anyone wanting one mallet pair to cover the whole keyboard range
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
Extra-large head
Wider contact patch spreads force across a big bar, pulling out fundamental rather than overtone.
Detail 03
Longer shaft
Extra reach across widely spaced low bars, and more leverage so you swing less hard for the same volume.
Detail 04
Lightweight design
Less fatigue over long passages, but you drive volume with stroke height rather than mallet mass.
Detail 05
Contra bass specific (FPY100)
Tuned for large tone bars. On a glockenspiel the head is too soft to produce a clear note.
Final check
Know before you order
- 01One pair. No bag, roll, or extra heads included.
- 02Yarn wraps fray with use — plan on rewrapping or replacing eventually.
- 03Wrong range for xylophone or glock; those want rubber, phenolic, or cord heads.
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01What instrument are these for?
Large tone bars — contra bass bars and the low end of marimba. The head is too soft for glockenspiel or xylophone.
02Can I use these on a xylophone?
You can, but the soft yarn head produces a dull thud with little pitch definition. Rubber or phenolic heads suit xylophone.
03How many mallets come in the set?
One pair.
04Are yarn mallets durable?
The four-ply synthetic and wool blend wears longer than plain wool, but yarn is still the first part to fray.
