If you like that guitar, get it.. try the pups.. If they dont do the job, then we can talk alternatives..
check out the audio clips.. they sound pretty good. Of course I don't know what guitar or amp they used to make the sound clips....

They sound pretty good from the demos I watched, I'd give em a shot. Schecter makes some good stuff for the metal crowd.
