I was and still am far from being one of the better guitarist for the Rock Band game as a whole (Bass is my instrument of choice). But one thing that did help me tremendously was that i have been playing using breakneck speed on expert, once you go back to regular speed and Rock Band it becomes infinitely easier ti hit the notes. With that said, in order for me to complete the solo guitar career from Rock Band 1 i still only have to beat Green Grass and High Tides, i survive for most of the song, until the final solo where i just crap out (i believe around 90% or so of the song) extremely frustrating.
EDIT: at the 50% mark and the 62% of the solo are my death knell on the last solo
Like I said before, it helps if you save your Overdrive for emergencies. Use it where you're about to lose and it should help you survive. GGandHT is a hard song alright, and its main challenge stems from how long the song is. It never gets as blistering hard as FwD does, but it's still a long song.
What do you mean "Is that Bibarel in my icon?" No it's not! Shut up! :P
