With this year's introduction of Guitar Hero: Aerosmith, Rock Band 2, and Guitar Hero World Tour, we figured it was time yet again to update our guitar compatibility matrix. With the introduction of these three games across three platforms, our matrix has gotten increasingly complicated and, for that, we apologize (but, really, if you've gotta take it out on anyone, it's Activision). If we've got anything wrong, leave a comment letting us know and we'll look into it. Otherwise, brace yourself for 96 color-coded info-cells.
Update (18 August): With new information, drums and Rock Revolution, we introduce Instrument Compatibility Matrix v3.0.
