My first 12 string was a cheap Italian Eko Ranger. It must have been 50 pounds. A real pain to carry around. Currently I own a Lowden made with Ovenkol and a Cedar top. In my opinion it spanks any Taylor I've ever played. YMMV.

My favorite 12 string belongs to my brother. It's an old { mid 60's } Gibson B45-12 as I recall. And if you can wrap your hands around the neck it has a bass response that sounds like a train rolling through your living room.

Now as far as 12 string players goes I'm suprised that no one has mentioned Fred Neil. He's the guy I always wanted to sound like. His old Electra LP's were classic.
