Guitar Hero: Van Halen

so can you use one van halen member for each of the 4 instruments...or does it have to be 4 different van halen members

Any Van Halen member can be used for any instrument. If you unlock Wolfgang first, you can use him on a guest song for bass, guitar, vocals, and drums and get the achievement.

Also, Wolfgang will probably be the person you will have missed if you don't unlock this achievement, being there is no achievement for playing a song with him.

That's not relevant to this achievement, silencer018. I unlocked this achievement before unlocking Dave or Alex. As I said, you only need to play on each instrument with a Van Halen member. If you unlock Eddie first, you can then use him to play a guest song on guitar, bass, drums, and vocals and get the achievement.

I should also note that even though I chose Wolfgang, Alex was on drums during the actual show, and Wolfgang was back on bass.

Hm... it could just be a matter of your selected character having to be one of the VH guys. The only reason I said to use non-VH songs is that simply playing a VH song on each instrument (before unlocking any of them) does not unlock the achievement.

So this is in Career? or Quickplay?

To exhaustively clarify, since I thought I had missed something, there IS NOT a specific Guest song achievement to be played with the Wolfgang character, as there are for Alex, Dave, and Eddie. Therefore, this achievement serves as the mop up for having played all characters on a song, ideally having also included Wolfgang on Bass at least once.

BTW you need to unlock the Wolfgang character for the other achievement.

Something's wrong here.

I just got the achievement, playing Panama with Wolfgang on drums. I had gone through the intro with the auto-kick on before I realized you don't get stars for that. I turned it off, played through Panama so I could get into where I could pick a rocker... and it unlocked right after the first song. I hadn't been able to get to the point where I could select a non-VH song in the drum career.

So clearly the idea about playing only non-VH songs is wrong. I don't know if you have to play all 4 instruments with the same person (I played all 4 with Wolfgang) or if you can mix-and-match.
