Developed by Klaus Bender, a dedicated cellist and engineer, who had been researching function and sound of a cello and double bass endpins. The KLAUS BENDER endpin is unique as to its material, form and function. In is exclusively manufactured in GERMANY.

Function:
The Klaus Bender endpin is not just push fitted into the instrument, but screwed into the bottom block of the instrument. The fine thread on the cone nearly doubles the area of contact compared to conventional smooth cones. Screwed in tightly, this allows perfect sound transfer between tailpiece, instrument and end pin. The improvement of the sound is unmistakable.
The rod in the Klaus Bender cone is tightened with a non-slip collet nut. Here the tightening force onto the rod is distributed evenly around it, thus avoiding any punctual pressure damage to carbon fiber or slipping on other materials. The thread is larger and more stable than is the case with a classical thin tightening screw on the side.
Four (cello) or two (double bass) diameters of the cone are available, so any instrument can have its perfect Klaus Bender endpin.

Material:
The cones of the Klaus Bender endpin and end button are made of aluminum. They have more mass than the regular wooden or plastic cones, a fact that has been tested and shown to improve the sound.
Weighing only 135g (4.3 ounces) the cello endpin with a carbon rod is still one of the lightest on the market.
Aluminum is not influenced by changes in temperature or humidity. The Klaus Bender cone thus firmly remains in the instrument, a big advantage for musicians who do a lot of traveling.

Form:
The big, non-slip collet nut can be safely used even with damp hands – and it still looks good into the bargain. The collet is easy on the right hand even for players with small hands.
