Agree with all about the personal nature of guitars. As Tom pointed out, even two guitars of the same model from the same manufacturer can sound different from each other (I noticed this when I bought my Guild F-212 years ago, choosing it over a couple of Martins and three other F-212s in the store). Have her take the time to play them and choose the one that suits her best, sonically and in comfort terms, ease of play, etc. Tom's post above is particularly helpful in this regard.
Guitar playing audiophiles, Martin or Taylor?
My "other half" is exploring the stress releiving effects of playing acoustic guitar. She's a great woman! She actually convinced me to buy a pair of Rowland model 9 monos w bps, instead of a boat. Thats my girl! Anyway, shes been playing for 1.5 yrs. Its a toss up between Martin ???? Koa wood, Taylor 314ce, Takamini GS330s, and a Tocoma???sound hole on top!!! All these models can be had "used" for around 900.00 All replys welcome, thanks Scot
