This arpeggio run is a favourite of mine. It sounds quite cool to my ear. It makes use of some Paul Gilbert style string skipping techniques which I absolutely love! Its not like sweeping (although short run has some sweeping pattering in it), but it has different kind of flavour to it when done correctly. Paul pulls his string skipping style arpeggios off flawlessly and they just sound divine!
This pattern is in the key of E Major and starts of with a Paul Gilbert'esque style string skip, some position shifting using a slide, single right hand tap/pull of combination and a C major shape descending sweep pattern.
Not that difficult to do, but its a cool melodic practice pattern for arpeggio practice.
