Guitar Tone from Hell

Been on my usual "delta blues" tear these past few days, and came across this little gem of Derek Trucks slaying his SG on some kind of radio promo with his wife, Susan Tedeschi.

Which made me think, if i was ever married to a chick who could sing the blues like she does, it would scare the hell out of me. I mean, how do you win an argument against someone who sounds like that?? Sorry buddy, but clearly your woman has the upper hand...
