This DiMarzio prewired replacement pickguard will fit into any Strat style guitar with standard 11 screw holes. Featuring the Smashing Pumpkins' frontman's signature BC-1 pickup in the neck, Chopper in the middle, and a BC-2 in the bridge, the neck and bridge pickup are a modified Air Norton S and ToneZone S respectively. On each pickup the frequency response of one of the coils has been lowered to give a deep sound from the low strings without losing any punch, and won't muddy the sound when you play through high-gain amps. The end results are the guitar pickups that are now in Billy's signature Strat. They do exactly what he wants in humbucking mode, and they work really well in split mode as well
