...i cant get it... I tr to hold my hand like he does but i just cant, my thumb is pointing more downwards while his thumb is pointing more upwards.. I try to have my hand lower but the n i mute the strings.. Does this mean my slap technique sucks? It works but it doesn' look as good as when he does it. Also, i hear how people talk about doulbe-thumping but he's not showing it in his video, and people call it the bible of slap. I thought you had to double thump to be good but he showed me i was wrong.
