I think it would be great if anyone who likes having a large sample database could add something in here...KVR is a great website to keep up with news & updates, but they have a lot of resources as well, such as a huge library of free stuff:

Word of caution: depending on how you intend to use "free" samples, you can get into copyright trouble. Many people don't read the fine print even on commercially released sample CDs-- it is possible, for example, to make a hit song using a loop from a sample CD you bought at Guitar Center, and be sued.

Speaking of loops is that what you're talking about? Or you mean, a guitar sound in a plug-in that you play using a MIDI keyboard?

Not free. :( Not sure where to get free guitar amp modeling software. I really like Peavey's revalver, but I've never used GTR3. My roommate has amplitube, it's pretty thick sounding, but not very genuine, at least with the tones he works up.
