I'm getting a lot of good practice out of the backing tracks from both the Blues and Gary Moore collaborations. Your tracks loop perfectly, and I use Reaper to make 15 minute loops and load them on my Roland, then I can practice jamming over them, pentatonic on the Blues, and major scale on the Gary Moore.
I am obsessed with learning the ability to jump to any box position on the fretboard and not lose my place, and I'm getting there and having fun at the same time.
Also working on bends, using the wrist action and not pushing with the fingers, and it does work much better.
