An endpin that improves the sound
The BENDER carbon fiber endpin is extremely lightweight. The carbon tube endpin by itself weighs only 60 grams. Combined with the precision made button, it allows for a particularly balanced and harmonic, but at the same time open and well focused sound.
The button, as designed by cellist Klaus Bender, is a unique piece of mechanic engineering. It is made of aluminum, and it’s screwed into the cello instead of just push fitted. Thus the contact between cello and endpin is much tighter than with regular wooden or plastic endpieces. The endpin is clamped with a fluted collet nut, which makes for comfortable loosening and tightening. The KLAUS BENDER endpin with carbon tube offers a rich, warm sound with beautiful overtones.
An end button for cello, to bring out all the sound that's in the instrument
The Klaus Bender button is precision milled from solid aluminum. It has a fine thread machined on the tapered end. Clamping is done by means of a large fluted collet nut. The endpin is being held firmly and evenly along its entire diameter. The Bender button is not just push-fitted, but also screwed into the cello. Thus the contact between the instrument and the endpin is particularly tight and even. The fine thread on the cone almost doubles the contact area, compared to regular buttons with flat cone surface.
BENDER standard aluminium collet nut for cello button
Original collet nut for the cello Bender button. Includes the plastic clamping insert for secure clamping. Note: Replacing the collet nut alone will not improve clamping, if the clamping thread is already worn out. In such a case, the entire button has to be replaced.
BENDER new brass collet nut
With its higher mass compared to the regular aluminium clamping nut, the Bender brass nut can improve the sound of the cello. The added mass interacts with the vibration of the strings, which are connected to the end button via the tail piece and the tail gut.
When the endpin can be removed from the cello, the Bender aluminium nut can be easily unscrewed and replaced by the brass nut. If the endpin is blocked at the rear end, please refer to your violin maker.
