Heres my take on this one...
Guitars recorded directly into the computer will tend to sound a little different to the sound you would get from your amp.
Also, recorded guitar lends itself to post production compression ,reverb,chorus etc - which will give a different sound to your amp with the same settings if you recorded that way... Try recording the same riff through your amp and then directly into your 'puter to see what I mean. My personal preference is not to record reverb but add it afterwards, as it tends to make the sound 'distant' - but I digress...
Out of interest, which sounds on andmoreagain's tune are you trying to get? It's a well recorded, nicely mixed piece that (if I'm not mistaken) has been enhanced with added samples and Midi generated strings - Beautiful, I agree.
