Also a technique that i think is more difficult than sredding is being able to play fast(above 140bpm) funky licks. Kind of like John Fusciante of RHCP but A LOT faster. It was quite easy for me to learn to shred at speeds about 200bpm but when I try to play in that funky manner I can go like 150 bpm and only for about a minute...after that I get relly sloppy
