don't give up just yet.:)
I get massively pissed of with tabs sometimes,but just persevere. Start of just playing the first two notes over and over and then go on to the next 2 then join those 4 and so on until you've got a whole lick. Have patience - this i lack :D.
Accuracy,you say? hmm interesting concept..
