Just started this. Trying to practice a few different techniques Prevent aching hands and all that with similar movements.
Definitely a far cry from the pentatonic.
It reminds me of those old video games where you would almost make it to the end die then die within 5 seconds on all your retrys...
Frustrating as hell but I can tell it is improving my picking hands coordination and knowledge of where the strings are etc..
The vid should defiantly say to start at 120bpm (was out of frustration

) cause I managed that pretty quickly although not first time but for some reason when at 60 and thinking about it more my coordination goes and I fluff notes or put the wrong finger down or just hit the wrong string with the picking hand. Finally I managed 2 clean sweeps at 60 last night my aim is to repeat that or better it tonight. LOL.
