DiMarzio DP225 BC1 Billy Corgan Neck Pickup  White 

When DiMarzio started working with Billy Corgan on the guitar pickups for his signature Strat, they sent him several models to try out. He liked the Air Norton S in the neck, Chopper in the middle and Tone Zone S in the bridge. After playing them on several gigs, he asked for some changes in the neck and bridge pickups. Corgan wanted a deeper sound from the low strings without losing any punch, and he didn't want the sound to get muddy with high-gain amps. To do this, DiMarzio lowered the frequency response of one of the coils in each pickup just enough to boost the bass while opening up the mids. The end result is this DiMarzio DP225 BC1, the ceramic neck pickup that's now in Billy's signature Fender Stratocaster.
