Re: The unofficial Rock Band thread.
Eh, I'm pretty decent at Expert and I don't even use the RB guitar. Another tip is to incorporate strums at the beginning of a pattern, whether you need to or not. This helps with consistency. If it is a bunch of triplets, strum the first note in each even though you don't have to. Now you don't have to worry about re-strumming when you miss because you will have done that already.
Sing glorious, victorious,
One keg of beer for the four of us.
Sing glory be to God that there are no more of us,
For one of us could drink it all alone. Damn near.
