As clean as you can get it, BB played a solid state fender, if my memory serves me!
"Lab Series" is what he was using both times I saw him---2010 and 2013 ---his sound is not a easy one to dial in..Think it was a Gibson Lab Series every time I saw him he was playing

LAB SERIES L5
Everyone knows it as the “B.B. King” amp, but it’s also the Ronnie Montrose amp—and the Ty Tabor amp. They can readily be had for less than $200 because people just want to get rid of them. It’s simply a kick-ass, solid-state amp. I like the immediacy of the older solid-state amps—they’re so punchy. The new digital solid-state junk is another story, but the old stuff is killin’. B.B.’s tone is great with the Lab Series. It’s warm and creamy and much more consistent than a Twin.

How's this sound? This is with a little drive and playing on the neck pickup.

A 339 or similar hollow body will give more air and more space in nailing that BB tone. Also light gauge strings, he used .08’s and a light touch on the fretboard exceptwhen nailing that monster vibrato. When they say tone is in the fingers, this guy wrote the book.
