Can I push down the pole pieces on my Fender Strat to make them flush with the cover?
It can be very risky to move the pole pieces in Fender single coil pickups without causing damage to the inner coil of the pickup. Breaking one fine turn of magnet wire will cause the pickup to fail. If you have plastic molded Strat style bobbins it is possible to move the pole pieces. If you are using staggered magnets and change the pole pattern, the inner-phasing of the magnetic field will be realigned and can change the sound of the pickup.
