[This isn't a store Chiaki comes to terribly often - at least not since she put Bard on the backburner - but she does stop in every so often to buy things to keep her own guitar in good working order. New strings and whatnot. Overhearing the conversation between Duster and his moogle, she blinks at them from a few feet away.]

...It's not that hard, really. Harps and flutes are more standard Bard instrument choices, but guitars aren't unheard of. If you get them reinforced, you can even use them as melee weapons.
