I managed to get to 94% of this song so far. If I don't complete this song on expert by the end of this week I am going to give up
Anyway I have a few tricks that may help some of you with getting past the 82% mark.
When the first set of triplets start I hold green and press red as quickly as I can (these buttons are the larger set at the top of the guitar neck) with my left had (presuming your right handed). I then, with my right hand press yellow and red on the solo buttons at the bottom of the guitar neck. If you time it right you should be able to get through the first set of triplets without using any overdrive.
I do the same again for the second set of triplets, but just move down a button.
When the quad notes arrive I hold down the large red button with my left hand and then press orange, blue and yellow (solo buttons) in turn with my right hand.
I am currently stuck on the fast orange, blue, yellow notes right towards the end of the solo. Even overdrive is not saving me just yet! Hopefully I will get through it.
I hope this might help!!
