Thanks, your a lot of help.
I've had to teach myself everything, ive been playing a bit over a year and i just want to improve.
My strap isnt that long at all, i usually wear the basswith the strings at the bottom of my rib cage, maybe slightly lower *im 6 foot 2 so the strap may look big because of that*
And i tried the 'thumbs up' technique for a while when i started slap, i just wasn't comfortable at all with it.
