Not troll bait, but why does anyone give a crap about their "signature tone"? I claim there is no such thing. Every player's tone is different at different venues, with different gear, even at different volumes. I love listening to isolated tracks sometimes, and the guitar tone might just make you cringe, but in the mix it sounds amazing. I think what we really strive for is "style". Any recognizable guitarist is recognized by his style. That's why we say it's "in his fingers". Yet people go out and spend $$$$ on gear to achieve a certain "tone" that's just not gonna be found except for maybe one perfect fleeting moment.
