Idk if this makes any sence but...
What should I look into if I want to hear guitar parts that sounds similar to Dethkloks in songs such as Duncan Hills Coffee Jingle and Thunderhorse?
I can't think of any bands that play like that so I need your help.

If you're going to flame Dethklok please step outside.
look in the section of that list about "melodic death metal"
Ibanez S520ex
Epiphone G-400
Roland Microcube
Alvarez MC90
