Customize your sax with a new Series II Alto Sax Neck by Selmer Paris! All of the new necks are now based on the Jubilee Series design which feature several improvements over the “Pre-Jubilee†necks. The new Jubilee necks have been optimized for improved response and resonance due to the lighter weight key mechanism and mounting system. Selmer has also removed the “guide†that used to be attached to the tube near the octave pip. There have not been any changes to the neck tube or the tenon itself so the Jubilee models will fit non-Jubilee Selmer saxes.
