Green Day: Rock Band

This solution is for the solo button impaired like myself:

Set your difficulty to hard, use the RB guitar, and turn No Fail on as stated by Markyshizzle and Orange Raccoon. Play thru the song (or dont if you dont want to) and when you get to the solo press all 5 solo buttons at the same time as each note passes the strike line. You will hit every note as it goes by and you will unlock the achievement at the end of the song.

Very cheap but very easy, took me two tries this way.

Following the above solution, doing career mode on hard is the way to go. YOU NEED A ROCK BAND GUITAR. It might also work with a different guitar if it's a guitar that doesn't require strumming to play a note. I cannot confirm this, as I did it with my rock band guitar. Just play the entire song on the lower keys so that your fingers are already down there and are used to the smaller keys by the time the solo comes up. When it comes up, it will start with a red note (if you're playing on hard, which I don't know why you wouldn't be, unless you wanted some extra challenge on the cheevo) that you need to tap and not strum. After this red note, just follow the rest of the solo through. It's really not that difficult, but if you need to practice it, just go into practice before playing the song. In practice, the solo starts with a blue sustain and not the single red note that actually starts the solo in the song, so be aware of that when playing. I'd also recommend that you know the part before the solo so you know when it's coming up. There's almost no time between the note before the solo and the red note that starts the solo, so you need to be ready. Good luck, and I hope this helped out at least a little!

Using a Rock Band guitar, you must use the small solo keys on the bottom of the neck of the guitar. When you use this, you don't have to strum for solos, just hit the buttons. You must get 100% on the solo without strumming. Hitting the keys extra is okay as long as the note registers.

With that said the actual solo isn't tricky at all, I got my achievement in career mode on hard. Just takes a long as time to get to the solo because its at the very end of the song.

Good luck!

"If you don't want to play through the entire song, you can turn on no-fail and still get the achievement if you only play the solo."

From the above solution:

The song is not hard, but The solo is at the end of the song, about 8-9 minutes in

How to do it without burning hours:

Go to practice mode and practice Guitar solo A until you get it perfect 3 times in a row, then the same for B. Then play A and B together 3 times in a row perfect.

Finnally Play the part before it, A and B, only worrying about the solo.

Once you are ready, memoized the part before the solo, and nailed it perfectly multiple times, Go to quickplay, no fail mode on.

Listen to the song and get ready When he says " To live, and not to breathe" get ready, because the solo is soon.

Good luck and hopefully you can get this in your 2nd or 3rd run

The only tricky part in the solo will be the descending triads. Make sure to slide your hand up for each second set of them and this should go by easily. The only true difficulty on this is the length of the song, you have about 8 or so minutes before the solo even appears.

i did this on hard expert is way to hard to do it took me 3-4 trys to get but you have to watch the screen real careful in order to get it if you miss 1 note you will have to do it again
