Can not get a good metal tone!

[Elute123]

I have been trying for a while to get a decent metal guitar tone. I bought a used POD HD300 and wanted something a bit better but still fairly cheap so I decided to grab an Eleven Rack. I am not happy with it at all, I can not get a decent tight metal tone. Everything sounds weird, I have some decent studio headphones and tried different stereos I have in my house. Sure, I need monitors but I can get tones using VST effects that I like with the audio setups I have. The treadplate sounds terrible sounds like it needs a tube screamer or something even after I mess with all the distortions. I have been messing with the DC Modern SOD but still not entirely happy with the tone I get. Any advice would be helpful. I want something I can use for playing 1 to 2 gigs a year and really want to just do digital straight to the board. Thanks
