I've created a 12 bar blues track found here

my question is, with the guitar fretboard showing, most of the notes being played are in the third or fifth position. I want BIAB to play them in the open or 1st position.

How can I force the notes down the fretboard so I get more of the bluesy tone? The chords are correct I believe, but
