I purchased 2 of these boards from John. I am looking forward to putting one in a PE car and actually playing the Hot Chocolate song. Bunmmer it was not in the Sound Hot Chocolate car Lionel released about a year ago. Not sure about the other board. I plan to put them around the layout and get mp3 files that will add flavor to a oparticular scene. Such as buses and taxis blowing horns etc....
Heckuva job John. This hobby needs sounds to go along with the sights. An added dimension.
