His solo releases, Bad Moon Rising, Lion, Live with Dio in NYC.. he's a beast.
I haven't really followed his Dead Daisies stuff, and didn't love his tone with Whitesnake. He's also gotten more "noodly" with his playing, vs the Lion stuff which seemed more composed - melodic, yet tasteful shreddy.
Great strat tone on his solo releases & instructional video, and I love his tone on Dangerous Attraction.
I have 2 friends who know him personally, and by all accounts he's a good dude. I've never met him though.
