freddie jacks 😯 If you listen you guitarists his I, IV, V boogie woogie runs in 1st position are variations with capo at 3rd fret I think his styly is simple but really effective due to the fact he just sings out let's it go and I believe most can do that given if they can stay in pitch and need that nachal' bluesy feel to em. He got that screeching insistent harp like his pops. I love his style, he is always sitting, I do too just preference no more than that! and if you play on the street much a plastic(light) chair is a necessity, I also like to use a strap adjusted short but not rediculously I don't have to rest guitar on leg and I got a small! wood box I keep beat with my heel, you'd be surprised how much color that gives your song, especially bluesy boogie woogie. 😯 Ciao
