I have a concert Kamaka that Jake signed on the front lower bout. I also have a centennial tenor and a 2015 tenor Kamaka. I am thinking about going to Elderly's Mighty Uke weekend soon. Chris Kamaka will be there. I would like him to sign one of my Kamakas. Should I designate my concert as my "autograph instrument" along with Jake's "Aloha Jake" or have him sign my centennial tenor?
