Pedal and amp settings?

Can someone please help me out a lil and tell me if I will be able to acheive the sound black sabbath has with my amp and pedal. I have a Peavey Classic 30 amp with a Boss metal zone mt-2. Oh yeah my guitar is a Washburn x-50 pro. I can get it close but still sounds funny with playing along with the songs. Thanx for any help.
