I recently find myself thinking after a Steel Stringed Silent Guitar from Yamaha as well...

The Aux In and Phones out feature sounds very useful around the house late at night when everyone else is sleepin... I've also heard them played plugged in, and they sound pretty cool.... I also like the idea of having a guitar to hump to gigs that fits in a small backpack....

Picked on up a few days ago at my local music shop, and I gotta say, I even liked the way it felt...
