I was all ready to upgrade to a RB2 guitar but it turns out all the stores around here got rid of them ages ago. I tried a GH guitar and I just can't play with it. The neck is way too thick and the clacky strum bar is just off putting.
Oh I definitely prefer the GH guitar. That mushy strum on the RB guitar is off-putting for me, and the whole thing just felt flimsy. The GH guitar has more weight to it, feels more solid. To each his own, I guess.
