She needs to be able to try them out for herself - buying online or unseen by the musician can result in having something where the neck, which might be great for somebody else, feels like shit or is the wrong profile for her hands and playing, so it hurts - I get that with Epiphone Dots, for example, but find Hagstrom Vikings an absolute joy to play, for example - Casino necks don't cause the pain that Dots do, either.
It's also a great experience to go into a shop and take your time finding what you like - good for developing assertiveness as well - and if somebody comes across as being like that, you can often get better deals. DD did it aged 10 with a stereo system - pointing out to the salesman that as a child, she had better hearing than he did, so should be able to listen to different ones just like the adults - he laughed, apologised and she did get a great deal on the one she preferred.
I have walked out of music shops where they didn't sort their shit out and speak to me with respect, though - it's my money and their loss if they don't think a middleaged woman matched their preconceived notions of a professional musician and sound engineer.
I'm not personally keen on modern Tanglewoods, but find mid range acoustic Corts surprisingly good (I have a Cort Bass that is very comfortable to play, has great pickups and is light enough to chuck about onstage - the Thunderbird bass I also have sounds amazing, but is a complete pig to handle, as I'm constantly fighting neck drop - and as I'm a shortarse, if I let go, it's likely to come crashing to the ground. It was a present - I wouldn't have ever bought it for myself if I'd had the opportunity to make the decision myself in a shop). DP's shitty acoustic, however, has the nicest neck and action of any acoustic I've played. It's still a heap of crap, held together with gaffer tape and an add on pickup, as the onboard one was shit, but I love playing it in the way the acoustic I was, again, given, just doesn't give me.
