I think your vibrato looks fantastic. Keep up the good work!
hmm, just feels wrong when i play lol or like im not getting enough back and forth in the tone. i guess thanks then lol!.
i didnt see anything wrong with your vibrato.

that is quite a slow piece though...i thought when you said fast you meant a bit quicker than that.

I think you have a pretty good handle on it. Vibrato is kind of like palm muting, it only gets better with time, and you dont really need to directly practice it.

heh well its faster compared to some other stuff. its actually prolly not even the speed but more the wierd (for me) change in hand postion so that i can vibrato. i was watching the music video where james does it and his is obviously a lot smoother but he also is able to pivot off his knuckle whereas i have to use the part of my hand at the base of the thumb.

palm muting tho...i never even mess with that as i never seem to play the songs i liek that have it in it hehe.
well...muting is pretty damn important lol, so start using it.
