LEGO Rock Band

This is a VERY easy achievement to get.

Most of the instruments in the rock shop cost from $50,000 - $250,000.

Since studs are very easy to get (just play songs and earn 5 stars [gold doesn't matter]) and then buy the most expensive instruments first.

All instruments have different instrument parts in the shop, but to buy the instruments, you MUST have the instrument in use.

For example, if you want to buy guitar/Bass guitar parts, you need to be playing with a Guitar.

This achievement is very simple. Even if you're a decent Medium player, it shouldn't take more then 10-20 songs to get 1 million studs. All you need to do is spend it all on instruments when you get the million. If you have any Entourage members that you hired that raises the amount of studs you'll earn per song/gig, then the million will come even quicker. It's just basically playing gigs/songs until you get a million studs. If you're playing Make A Setlist gigs, and you have DLC, play Thank You Boys (Nothing's Shocking album, 160 MSP alone), or Charlene (I'm Right Behind You) (Free) with Song 2 and A-Punk. You'll blow through those gigs even faster.
