Thanks for the info Slipin, its true he is exceptional player,but i tend not to take any notice of that these days as it can put you off thinking, "i'll never be able to play like that" ;-)
so its to do with Amp, one of those really expensive tube ones thats probably way out of my price range for the skill level im at..
Its a beautiful sound that, keep listening to it, its really inspiring to watch a great player, specially one thats not shredding all over the place..
