I'm not keen on Fender acoustics at all. I opted for a second hand 12 string, and I got a 1970's Hohner Leyanda LW-1200 N. Its a lovely guitar. Herringbone top and back, abalone rosette, bound neck and headstock, mahogany back and sides and a solid spruce top. I'll be fitting a piezo soon no doubt.
Anyway, I tune mine to DdGgCcFfaadd, to relive tension on the neck and strain on the top. It's quite an old instrument, so I think it's better i do this. I'd advise tuning down to Eb or D, and just using a capo.
