Hi Johannes,
This is a great idea! I will do a One Shot lesson on this as soon as I can! In the mean time, play along to some of the practice loops with just your left hand shuffling. But bear in mind, that is implicitly somewhat difficult. You’ll probably notice that when you add your right hand playing the chop that the LH shuffle will get easier to play. They naturally work together. (This is also true when you switch hands.)
This, no doubt, will be discussed in the above mentioned one shot.
Keep on …..BUBBLIN!
