These things are amazing. Installed with a blend circuit, my guitar growls and screams just the way I wanted it to. Anything from blues and stones to mastodon with these and a decent tube amp. They completely live up to the hype. Told my wife the sound I was going for was "jangly balls", after she got done laughing even she could hear the difference. I now have the perfect sleeper rig, everything looks stock and simple until I crank it up and turn heads.
