concerns were bought up about EM machines ! well if you keep warm white under PF and do some highlighting on the PF it makes a HHHHHUUUGGGEEEEE difference and people tend to be drawn to it and play it more ( as they should )
I must admit though that when I get around to doing 2001 ( 1971 GTB ) I will keep this all warm white purely for nostalgia value and I do find that using the sealed 44 base in this tends note to strobe as much ?? don'y know why !
