I run my JC basically the same but with the treble rolled off to about 11 o'clock. I'm on the road currently for work so I don't have the JMP-1 settings handy but will post them here when I get home. Short version is that a nice warm clean tone gives you a very immediate and present muff tone that doesn't have much sag. If you run it into a crunchy setting on the JMP, you get more of a high gain distortion tone with some nice sag. Both are very musically useful.
