My 620/12 has been my "go to" gigging instrument for a long time now, but having tried a 6 string version at a local music store many months ago, I fell in love with the timbre and feel of the 350. It has taken me a long time to track down a 12 string version, it should arrive here in the UK next week and I am over the moon at the thought of being able to gig with this beautiful guitar, and hoping for some great sounds.
I have heard there can be issues with the older "vintage" style tuners, but keeping a 12 string in tune can be tedious at the best of times, regardless of the tuners!!
