My mid 1960's Guild 12 string big body has a voice that is so sweet, and an action to die for. I love this big old guitar, and based on my experience, I would say they are the gold standard among production 12 strings. I have played Taylors, Gibsons, Seagulls, and many others. None have the same overall quality as my Guild. If you can't afford to have Nick Appollonia or Grit Laskin build you one, then grab one of the older Guilds. They are heavy buggers with that double truss rod, but the sound and playability is something.
