A good friend of mine, who is the lead guitarist in a decent rock band, has one of the Daisy Rock "Flower" guitars (her boyfriend/bassist got it for her as a "gag" Xmas gift) and she tunes it to "Open E" and plays slide with it on several songs in their repertoire...it sounds really decent, too!

Daisy Rock has some great ideas about inspiring girls/women to play, and that's a very good thing, IMHO! ;)
