Tenor is 12 inches, Concert is 11 inches!
Length of body.
Does that help?
Any more measurements that you might need, let me know
I sell Kamakas and have a bunch right now.
I have a measuring tape and know how to use it
Haha!
(And yes, I just dropped that I sell Kamakas cause yall know I am proud! I find ways to bring it up in casual conversation... haha)
