The Klaus Bender Endpin

The Klaus Bender Endpin from Fiedler - made in Germany 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 in sound is unmistakable.
The rod in the 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 puncture 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.
One violin/viola button, four (cello) or two (double bass) diameters of the cone are available, so any instrument can have its perfect Bender endpin.
The cello endpin diameter is 10mm. So once you have your Bender cone fitted, you are free to use the different rods according to your tonal preference.

When you first use the Bender pin, it may appear to be stiff, and difficult to use. This is because the small internal grey cone that clamps the pin into the cone needs to be released each time, and this "release" is simply done by opening the knurled knob a little further until a small click is felt. This "click" is the clamp cone releasing from the alloy fitting, and when this is felt, the rod is free to move.All you need to do until the pin is fully bedded in is to open the knob a little more than you would initially expect in order to release the cone, and the rod will move freely through the alloy fitting. Once bedded in, the action becomes smooth. For more information, please contact  us.
