I own a very non-typical '72 Thinline RI--all the details here: http://www.thefret.net/showthread.php/22055

I like the guitar VERY much. Killer looks, very comfortable to play, and the tones seem to split the difference between regular humbuckers and single coils, though I'm sure that a part of that is the upgraded Novak WR humbuckers. The aftermarket Bigsby is very cool, as well. The other guitar player in our church praise band owns a newer '72 Thinline RI with the 3TB finish, all stock, and I've also played that one a bit. Not quite as bright & chimey as mine with the Novaks, but still a very good sounding guitar.
