J uses natural vibrato and bends notes all the time and plays double stops which means more than one note is being played at a time, plus the tremolo and effects. So his notes are not as precise as say the cleaner allman brothers but that is not what he is going for. Thus I agree he rarely hits a wrong note or should I say rarely ever doesn’t sound like J. But he is sloppy sometimes, like that Slim’s recording is pretty sloppy.
