I haven't heard anything about long scale Kamaka tenors.
However, I believe SouthCoast ukuleles builds all of their ukes (including) their tenors with scale lengths one size longer than usual (aka: soprano size bodies have concert size necks, concert size bodies have tenor size necks and tenor size bodies have bari sized necks).
Kamaka did come out with long neck concerts and long neck sporanos. You can see them at the HMS website. I haven't heard anything about a long neck tenor.
Shootz, if you live ova dea, do what Stan wen suggest. Call or go visit da stoahs an askem. HMS in Wahiawa, Dan's Guitar's (corner of McCully and Beretania) and Kamaka stay on South St. and all da odda stoahs.
Mahalos for the replies. and yes, coming from Hawaii I wish I could visit all these fine places but my current location is in Japan so I hope to find one online.
