Need pics of these sweet metal machines! To answer the original question, I echo those that say the signature model may have unique specs some of us want but we don’t necessarily care about the guitar being somebody’s signature. I used to be against them but now I own two. A Kirk Hammett KH-602 because it’s neck thru, high quality, and came with the new bone breaker pickups ($200 EMG), and I bought a fender Chris Shiflett because I liked the look, the standard sized humbuckers, the 12” radius rosewood board and 70s style tuners. I may mod the Shiflett tele at some point. No need to mod the KH unless I want an original Floyd rose on it. Am I a KH fanboy? A little. Am I a fan of the foo fighters? Not really. Just like the guitars but haven’t modded them.
