Original TUNE designs were created by Hatsun Fujitani in the 80's, hence the Hatsun in TUNE model names. He is still working closely together with WSC in Korea in developing new TUNE models.. Like the brand new TUNE Serengeti Bass and few other prototypes that I saw TUNE exhibiting at their 2015 NAMM show booth in Anaheim this past January.
You can see the new Serengeti in the right side of attached picture.. and a brand new model prototype in the middle (between me and Hannah from TUNE), both of them designed by Hatsun Fujitani.Link Removed
Also, TUNE Korea is exhibiting on all trade shows.. NAMM, Frankfurt Messe, Shanghai .. etc.. Where the Japanese company that uses TUNE name is not allowed to do so.
