Re: Polepieces and spacer material
Oddly enough, using 12 pole pieces will tend to make the pup weaker. We were just discussing this in another thread somewhere, and its in one of the Seymour Q & A's. The screws, extending out of the bottom of the pup, will shift the magnetic field away from the strings, making the output weaker.
Its the reason that all the SD schematics show splitting a humbucker to the stud coil. Its a stronger magnetic field.
Ever since I read that, I've been meaning to cut off the bottom of the pole screws, (after tweaking the heighth), just to see if I could notice a difference.
Don't know about the spacer.
