How to unlock the Burnin' a Hole in Your Pocket achievement in Guitar Hero III - Definitive Guide
Now, this is almost an unachievable achievement for most of us. You will have to buy everything, inlcuding the items unlocked through completing various careers. You get one guitar for every difficulty, 5-stars on every difficulty and for co-op careers. You will have to unlock all of those before you can buy them, and you can get this achievement when you do. Good luck.
