For covers, close is good enough in most cases. Every band I've ever been in, most of which were cover bands, none of them every played a song note for note like the artist.

The old adage of "Make it your own" holds true.

In this case, BB/RB will get you there in fine fashion. I've used it to recreate a few covers through the years and they came out amazingly close to the originals... with my twist and signature on them.

You can make excuses or you can make progress but not both.
