No, they are not threaded and nor do they have an Allen key socket unfortunately.
[quote name='Lfalex v1.1' post='68944' date='Oct 3 2007, 09:27 AM']Why do you need to adjust the pole-piece height?[/quote]
I like the contour of the strings to match that of the fingerboard, and my Willis basses have got me accustomed to a pickup that does the same. I need to alter the pole pieces firstly for consistent string to string volume as you'd rightly guessed, and secondly because I sometimes catch my fingertip on the edge of the furthest G-string pole piece...
