YAMAHA Compatible ART Kobo Rosewood Thumb Hook, Thumb Rest

ART Kobo Nob - L-shaped Rosewood Thumb Hook and Thumb Rest
For Yamaha saxophones.

Offers better resonance than plastic thumb hooks and a softer, rounder tone than metal ones.
I used it on my alto and baritone saxophones, and it blended exceptionally well in ensembles due to its woodwind-like resonance.
The thumb rest was cracked in the center and has been repaired with adhesive, but this does not affect its use.

From the official website:
Wooden thumb hooks and thumb rests are made from materials with a gentle feel against the skin.
The sound image is a balanced tone that doesn't resonate as much as metal and has more definition than ebonite, making it suitable for a wide range of applications.
