That's kinda what I thought - to enable singing on the 1st & last verses, then wild (!) soloing on the middle verses...I haven't set any of them to 14 x's thru to see what happens, just working today on a couple of quick 3 x's thru audio practice tracks for one of my students. BTW, iReal is AWESOME for teaching the Blues to this eager 12 yr. old student, who can already improv on the piano, but wants to learn to play the Blues on the guitar. Thx!
