fret spacing of soprano

i wanted to know how much difference is that space of the fret for soprano compare to concert.

and also would you recommend a kala sprucetop with side cut or a kala black glossed?
they're both have pick ups btw

I own a soprano but not a Kala. I've played the black gloss but I prefer cut instruments. I believe ur good either way.The fret spacing is a little smaller but I say even enough for ur fingers, and I suggest the Kala Spruce with the cut because it makes picking along the higher frets a breeze.
