that is his new stratocaster verison...different pick ups..hard tail. so different from the Born To Lose guitar.
his real signature would be the '57 reissue one with the 3 lace sensor pick ups ( red silver, blue ).
the new one has dimarzio pick ups.
all the fans know that to be the billy corgan strat; if you want the SP sound that's the way to go.
if you want to replicate the newest live sound otherwise the new strat is more indicated.
