I also made sure to try and fix any muting issues. From listening to the isolated guitar track of the solo, my interpretation of it is that the ascending sweeps (when I go back down, vertically) are faster than the descending sweeps, which is why I sweep faster when ascending. It's also extremely difficult to time the arpeggios into the sweep, which is why I only played two arpeggios instead of three before the first sweep (I can't spend all day trying to get the perfect take). I also cut out the economy picking section towards the end, because the amp started bugging out. Maybe I can use this as a standard for comparison when I try the solo again later.
