Lowdens are about the brightest, most jangly guitar you're ever likely to meet, so *not* Lowdens!
I've played a Guild which exactly matched what you described - thumping clean woody basses, but trebles a bit lacking. Try one of those, maybe. Or for woodiness, if you're in the States then you might be able to get hold of Tacomas - they've got a nice woody sound to them.
A good Gibson will work. Mind you, there seem to be quite a few uninspired Gibsons out there, so make sure you get one of the good ones. Also Gibsons tend to have a large markup over other makes, which is often unjustified by instrument quality. Or you might look at Collings or any of the high-end Martin-alikes.
