it's simple: get one of these:
and play something slow and gradually build it up until you can shred to the click. the note variations are fucking insane, especially going in triplets. sounds fucking sick as shit when you're just jamming some metal as fuck riffs that go down, down, up picking wise. i don't know how i lived without this. they're $50 ($80RRP) at billy hydes at the moment so get on it!
