what are you using to get that tone? i really like it. as the above said, there were some slight (and i mean slight, very passable) timing issues (specifically at the ending of ending of every verse riff i noticed i think) so just clean up the timing a bit to make it fluent, you're pretty close already though. the solo could use some practice as well (i know it's nirvana so it's kinda supposed to be sloppy). great cover though, getting close to perfect
