If you aim to surpass these scores you'll nail this achievement, some of these can cause trouble for even the more pro players if you find that you're struggling, make sure you're using star power in the best places, these are normally the heavily corded areas and such. Looking on Youtube and watching an uploaded video as an excellent idea to see when you should be activating star power.
Play with which ever guitar controller you feel most comfortable with, personally I use my GH:M controller and lastly don't be afraid to use the Hyperspeed cheat.
On the main menu (the one which lists career, quickplay etc) press; "Blue, Orange, Yellow, Orange, Blue, Orange, Yellow, Yellow". It will space the notes out further and make it easier to distinguish them in the faster solo parts etc. (While it spaces the notes out by speeding up the rate at which they come down the highway, it doesn't affect the songs tempo in any way!)
Thank you to
