The Etude makes it possible to move the pressure point of the thumb rest to the first phalanx of the thumb to the space between the two joints. The lever momentum is much smaller at this point so the thumb can support the weight more easily.

Much of the energy used for supporting the weight then becomes available for handling the instrument.
And can be used to improve control and speed up paying technique.

New features: 

• The Etude3 has a new metal hook covered with soft rubber and a casing with improved ergonomics.
• The hook is adjustable in height as well.

There are several hidden features to improve the physical strengt of the design such as better materials and a redesign of dove tail slide and mountingslide.
