get a 81tw( new
COIL TAPPING version) for the bridge and a 89 for the neck and a SA for the middle
the one thing that the EMG's have over the duncan BO's is that they can be split for a SA tone
FWIW, the 81 sounds more evil than the much BO bridge pup IMHO
like the other poster said the BO is a hotter ,warmer passive tone in a active
they are great but the emg 81 in the bridge just sounds more metalic metal
the BO bridge pup is like killswitch(real thick and warm) and the emg 81 is slayer,zakk,metallica(crunchin,kicking,present,and generally aggressive)and all the others that use it
