Cool man, you've got the chops I can hear it. Just the metronome again. Pretty nice for a cellphone recording!
The thing with the metronome is it prepares you for the recording studio (or stage I suppose), where two guitars have to sound like one. Here's my two-guitar attempt with a clicktrack set at 208 bpm:

The point is, those guitars have to follow the click pretty closely or at 200+ bpm, things become a MESS. (Indeed mine is probably not as tight as it could be. Oh well. Real life calls, gotta run!)
