I too have a PRS Tremonti. While I haven't played one, people seem to say the Painkiller sounds the closest to the PRS Tremonti treble pickup, so that could be worth looking into if you want something tonally similar. But, I think Dave's suggestion of the Holy Diver might be right on. The Holy Diver is hot enough to keep up with the Tremonti Treble, but it is tonally different. It has more low end and is definitely fatter. The Holy Diver could cover Tool and Alice in Chains better than the Tremonti. For the neck, the Emerald is a classic pairing. It is more vintage voiced and very fat and fluid sounding, great for solos.
