Sounds like a real guitar because it is!!
Also, when you mentioned the icky high notes, sometimes, when you play live, and you're on a roll, you tend to leave the recording as it is. I'm not saying he did that here, just saying that sometimes, when you play live, and you're on a roll, you tend to leave the recording as it is, because it's a pain to record over, especially if the solo you recorded was long. Anyone who's recorded a long solo live knows what I'm talking about; unless you're a virtuouso unlike me.
Yu- "Eric," I mean, (whew, sounds a little weird), may not submit a lot of mixes, which is why you have to go his site and get em! Especially check out his originals. http://www.gamemusic.ca
As for the arrangement? It's awesome, the mixing is great; the sound quality perfect, the atmosphere gives a much appreciated nostalgic feeling if you've played the game, or even if you haven't, heh. In the time it took you to read this post you could've downloaded this, so don't waste your time!!
