Ahh, credit for this sort of behaviour must go to "Weirdy." He put me onto the evilness of splitting the wire from the pick-up closer to the neck and running both wires (extended) to and from a push pull pot. It puts the two pick-up segments, as a P Bass pick-up is basically a split single coil, in and out of series and parallel.
There is a noticeable drop off in sound out of the pick-up in parallel mode.....but I like the roundness of that sound for blues and slower songs.....like an instant tone drop of known proportions....that you don't have to roll a knob up and down and try and find a sweet spot....instant response.
All hail to "Weirdy"the King of wiring. Thanks Scott for all your electronic guidance. Did it all myself this time Dad....
