I've always kept the tone control on my passive P and J basses rolled back a bit. After seeing this Pbass vid from Scott Devine.... http://youtu.be/eoVfamlcbYo ........I've been experimenting with rolling it ALL the way off on the P (Classic 50's, 62 Original pup). I dig it. That's the P tone I hear in my head. Am I fooling myself about that woofy a tone working in a live situation, though? Seems ok in rehearsals, but I haven't gigged it yet. Anyone else run their P that way? Whaddya think?
