Ding dong! That would be the normal sound of a doorbell, or some folks might opt for something less traditional and target a more natural sound, maybe that of a bird chirping. However, how about taking a slightly less traveled route with the $129.95 GuitDoorbell? Yes sir, the GuitDoorbell is not exactly the standard issue doorbell that rings, but rather, it works more along the vein of a door chime which will make a sound each time the door is opened or closed. Coming in the shape of a half-sized guitar, the GuitDoorbell is mounted above any inward opening door, where a striker will strum the guitar each time the door gets into action, now how about that? It does look rather unsightly IMHO though.
