I’ll cast my vote for Brad Paisley. Here’s how tasty his playing is - I don’t even like country music but I consider him my favorite electric guitarist.
Here are 2 of his more accessible tracks for people with more of rock preference:
His tone is ridiculously good (and he has several different tones that are all uniquely “his” sound). He never sounds stock, because even when he plays a cliche lick, it’s always got some type of personality or inflection to it. And he’s also super melodic. I had the privilege to see him live (the only country concert I’ve ever attended lol) and was blown away. Everything was improvised, but still extremely controlled and every bit as inspired sounding as his recordings.
It’s weird to say he is underrated, since he’s so popular in the country music scene. I just never hear about him in shred circles and he’s definitely an EJ or EVH caliber player.
Whenever people ask me who my favorite guitarist is, I tell them “Eric Johnson…until I heard Brad Paisley”
