Look bro it takes time and experience . NOT GEAR and GEAR REPLICATION. I have a brother who has played in a very popular metal band for 3 years and have played myself for over 26yrs and i can tell you it comes with knowledge,research,andtime period. I mean for christ sake Jimmy Paige recorded his most fampius guitar parts on a beat up Telecaster thru a very small supro amp and on Black Dog the mofo didnt ebven run it thru an amp he plugged straight into the board. There is a reason thre are professional mixing engineers its bcause they either go to school or have done so miuch OTJ raining they are OGs and some just have a gift but u can listen to whoever and buy and use whoevers gear you want the main #1 problem is you are not THEM no matter what u do it wont happen. I saw an Ozzy/Alice in Chains show in 94 when Dirt released and i watched Zakk mess around and pick up one of Jerrys G&Ls and play thru his rig and u know who he sounded just like ZAKK .
