Re: adjust bucker poles??
Pole pieces are adjustable to act as volume controls of individual strings; it has nothing to do with the neck radius.
Plain strings are louder than wound strings, and thick strings are louder than thinner ones. Therefore the G & low E will be the loudest, and those pole pieces should be the lowest. The D has the least volume and should be set the highest. The high E is the next weakest, and the pole piece would be almost as high as the D. The B should be set almost as low as the G, and the A in between the D & low E. This equalizes the volume (unless you have a wound G which should be set even higher than the D).
Without equalizing string volumes, you may notice some strings are more prominent than others, not that it will ruin a song or a solo. Adjusting pole piece height is more of a fine-tuning thing, instead of a necessity. But why not do it?
If you want to emphasize your high notes in solos for string bending and additional sustain, you can simply set the the D thru high E "up", the low E "down", and the A in between the D & low E. Another advantage to this is that if you set your amp EQ warm (like I do), it keeps the two low strings from being too bassy.
If your wood brings out certain EQ's, you might want to adjust your pole pieces differently to fit your guitar.
