I suppose that's another 'slant' (pun intended) on altering the internal profile of the tonehole ! There's something wierd along the lines of "reducing the size of a tonehole, as well as optionally building up one side to theoretically 'move it' a tad, has the same effect as raising the open height of the pad". In this case I'm talking about the open LH 'B' pad, which has some bearing on the pitch and clarity of the crossover front C.
I also prefer the pitch and tone of the side/palm "ballad C". It's all a question of balance. Or voodoo.......
