I can play Pink Floyd's "What Do You Want From Me?" but I've been trying to really get the tones down for the song. I'm not certain what David Gilmour used in the song to get the sound that he did on the solos(especially the intro). I have a Line 6 TonePort GX(Yes, I know, not the best at all). Would anyone have any idea as to the effects used. distortion levels, etc. ?
