I was sold on the concert, but in the last few months I have moved to tenor in a big way. I play it on claw hammer and bluegrass music. I like the sound of the concert better for both styles, but it is just easier to play with the tenor neck.
My browser inexplicably crashes every time I try to put my vote in, so I'll put it here for now. Right now, soprano and baritone. I'm really hoping to add tenor to that list soon. I do have access to my dad's concert Kamaka, but I usually prefer to stare at it on the wall.
I only play tenor now....but tried all of them before.....except baritone!!! But I would like to make Luis from LFDM build for me a concert size uke.....which would sound big and full!!!!
