bossgtcentral.com sir...that entire site is more tutorial than you can ever hope to implement, but they have a few starter guides as well.

EDIT - there's a guy on there by the name of TeeJay (I think) that produced a great tutorial DVD for both the GT-6 and GT-8. If you really want to use the GT, you couldn't go wrong with spending a little scratch on that.

Oh and buy a Midi Cable for it, so you can import patches from your computer to the Gt-6. It works wonders! bossgtcentral.com is the way to go as twostring said.
