i tried emg hz's in an esp h-301 and they sounded like complete crap. It was a lot of midrange with no defenition. I would stay clear of them. The real emgs (i prefer 85 and 60) are quite good if you want the 'active' tone. If you dont want to spend the extra $$ for actives and the hassle with a battery then i would suggest finding some duncans.
