Hi,
To be honest I never changed pole pieces heights as I was only playing with pickup heights adjustments until today and... it`s worth the hassle.
but long story short...
I keep my both bridge CBomb and CS neck quite low, but once I noticeably raised all pole pieces on both pickups (a little bit over a half of turn) it has brought both pickups to life.
It added overtones for sure and made pups sound less 'dull' and a bit brighte and clearer I suppose.
In my opinion lowered CBomb/CS with slightly raised pole pieces helps a lot.
has anyone got any other thoughts/suggestions about adjusting BKPs in general, and CBomb and CS in particular?
