My old school had one, personally I preffered using a proper classical guitar. That's not too say it was shit at all far from it it was a wonderful guitar to play but I just didn't like the way that it felt in me and it was a bit odd too play and get used too for me and it sounded alright but I can't remember the exact specifics of the tone. Actually I probably couldn't think of too many applications where it would be needed considering you can get any acoustic guitar to be very quite but I'm sure there's a market for it.
