Had the blackouts installed yesterday. Holy crap. This is sooooooooo sweet. They are in an ESP Horizon NT ll that used to have jb/59 combo. I a/b-ed it with an identical guitar with the jb/59 combo and OMG. Blackouts = sound on jb/59 = sound off. Ridiculous power with balls 'n all. To wrap it up in four words: Balls, brutality and sweetness. I also a/b-ed them with emg 81/85 combo in a very similar guitar and the result is that the emg's are slightly hotter but lack in tone. The blackouts on the other hand Have it all Balls brutality and all this sweet sweet tone.
