Band Hero

I never thought I would be able to get this on my own, and with very few people playing online at this point I figured it would require an arranged online play time with someone. Then it happened on it's own using a guide here for getting 11x multiplier by yourself...

So I'll repost it here for all to use.

Do a quickplay of the song Sugar We're Goin' Down (Fall Out Boy) with 2 vocal parts and 2 guitar parts. Set everyone to beginner.

I used a microphone and a 360 headset with a fan blowing on them for the vocal parts. As you know this will get you 100% for those parts. I kept the two controllers on the ground next to two guitars that were laying flat on the ground. With the guitars on beginner all you have to do is strum them, so strumming them both won't be too hard.

After the second band moment, wait for the short break in the guitar parts and then activate star power on all instruments (back button on the guitars and a button on the controllers). Not only will you get 11x multiplier immediately, but then keep playing the song and you should end up with over 1.1 million in points.

Enjoy!

Note - you may or may not need to get the full 11x mutliplier for the 1 million points. So if you only hit 9 or 10 times multiplier finish the song anyway just in case.

I earned this achievement on by myself. All you need to do is put on 2 mics on beginner which will be 100% and guitar on medium which you only need 93% and you'll end up with about 1.7 mil or you can do one beginner mic, again 100%, and hard guitar and you'll need at least 96% and you'll get around 1.75 mil. Do this on American Pie.

I was able to get this one on my own, along with the 4 of a kind, there's no I in band hero, and the 11x multiplier. I used one mic, 3 headsets in front of a fan on expert. I used the GHWT import of "no sleep til brooklyn" and got 1.3 million points. There's also 2 band moments to get the 11x multiplier. If you don't have that song, American Pie will get you 1.6 million and there's I believe 5 band moments.

If you have the Death Magnetic DLC, you can get this on All Nightmare Long, with a beginner mic in front of a fan, and you on expert guitar, it may be possible on hard as I got 1.4 mil on expert, but expert is easily done if you can play the song.

I got this on Don't Speak by No Doubt, with two players on Expert Guitar and Medium Vocals. It's a fairly slow and uncomplicated song to sing, so as long as you or someone you know is good at guitar you shouldn't have trouble scoring around 1,200,000 points.

i managed to do this with 3 mics on beginner and guitar on easy and only used star power with the guitar and got an easy 1.7m from the dlc song afterlife from aveneged sevenfold

if like me, you have no access to a fan, can't get it to work, or just suck at singing, there's still hope! I got it easily with just 2 people.
I played on hard Guitar and my Girlfriend played on easy, playing American Pie, we both got around 97% and still managed to get around 1.2 million points, and that's not bothering with the highest multiplier possible, just casual playing.
Hope it helps
