Nice!
I don't geddit, what's so horrendous about playing Mustang Sally? Playing one bass line over and over is a style element for some songs. I have no issues with extremely simplistic bass playing, ostinato, that gets you heard and noticed. Or complex bass palying. What I'm not so crazy about is the stuff in the middle, like - groan - followinging the virtual rhythm guitar chords note for note bar for bar. There is no reason to play to guitar harmonies of A Minor, F Major, D Minor/Major and C Major anything else but one grinding A throughout. Get's you noticed more than that degrading harmony hopping. We're not the E string of a bar chord rhythm guitar, you know!
