pretty accurate playing! the guitar tone is a matter of taste, i guess the jam track is cool! you've been listening to the dev for a long time, haven't you?
I agree with Ike, (if I may guess as to what you meant, Ike)...your tone is a little "hot". The input needs to be taken down a little, and so the gain, for it to sound the best it can when recording. BUt, I thought it was a pretty cool cover, nonetheless.
but the playing is indeed pretty good! if you'd like to record stuff and you don't have a good rig, check out Revalver MKII, you can record stuff line-in and reamp everything, and it sounds uber tight ( http://www.alienconnections.com )
I'm not sure of the restrictions for their demo though
