Rick, she uses a few guitars. Her main one is a Daion, sorry I don't know the model number. It's an odd shaped guitar, an acoustic with a cutaway and an oval soundhole. It's tail is shaped kind of like an acoustic version of the Gibson SG (?) Electrics. If you look closely at the bottom right picture here

you can just make out what I'm describing. She uses an open tuned Yamaha as well, a very normal acoustic guitar.

She is sometimes accompanied by my other sister who uses a very traditional Goya.

As I said earlier, the first step will be to try an omnidirectional mike, but I have printed all of these posts and given them to her. I'm sure that this shared wisdom will solve the problem.

Thanks again to everyone.
