Peavey Butcher for good Thrash tone? Tell me what you think?

I'm Ordering a Peavey Butcher 120w tube head this weekend and I was wondering if any of you have played on one of theese before and if theyre good for Thrash metal? I have a Epiphone Flying V with an Emg-81 in the bridge and and i would be running it through a randall 4x12 cab. I also have a Boss MT-2 Metalzone distortion pedal and a MXR -108 10 band Equalizer I could use if that would help my sound. Its either buy the butcher or buy a decent tube pre amp to run through my randall RX 120D head somthing like an ADA - MP1 preamp. Witch of theese desicion's would be best for overall good sound and loud voulume?
