Hi guys, I may be purchasing a 7420 soon and there are a few things I want to change: 1: The trem - What type would you recommend to replace it with? I'll be adding a tremol-no but want a good trem for when I'll be using it. 2: Pickups - What set would you recommend for metal? I'll be using it for other styles as well but mostly for metal, would a cl/lf be a good match? or a D-activator and Liquifire? Anything else you could recommend to make this guitar even more awesome? I plan on making this axe last!
