It's too bad he can't afford a new guitar? I may push your vox just a little bit harder in the mix (at least a few db...) They don't feel quite out front enough to me. In some places they do, but in some places they need some love and should be on top of the track. Good job on the performance. Amazing guitar work!
It would be nice if you had the original track so you could pan and EQ that lead guitar to move it out of your way in places.
That guy is really an amazing guitarist... He's a freaking prodigy. Not many people can play like that, only a handful.
