Love my Grand Concerts, especially my short scale 412e-R, spruce over rosewood, X-braced.
I find it almost too easy to play this guitar, and it produces fantastic sounds. I just have to be careful not to overdrive it.
My other grand concert is a standard scale all mahogany with a cutaway.
Just my thoughts on Grand Concerts, but I have no minis or GTs to compare them to. Just happy with what I've got.
