There is no gray area when it comes to Slipknot guitarist Jim Root’s vision for his signature models from Fender. It’s literally black and white. 

Sure, only black and white finishes for the electric guitars in one respect, but more importantly, there's equally no gray area in each instrument's concept. If anything, his signature instruments clearly sport the bare minimum to get the job done, and Root undoubtedly loves using Fender’s iconic shapes without any of the bells and whistles associated with their original formulas.
