A friend who is on the PRO side of the music/recording business just bought an inexpensive classical guitar and explained that he was going to 'open up' the grain/sound with an 'electric vibrator' (I asked him if it was really a dildo) - a 'secret tip' he had got from some pro guitarist. I sent him the link to this device, he was not surprised that someone made a business out of it.
