Several touring acts have participated in our development of this method of attaching a Helpinstill Grand Piano Sensor "permanently" into their touring pianos, among them, Kenny G. and Willie Nelson. After several years of their successful use on tours, we decided to develop a version that anyone could install to get this advantage of not having to remove the pickup to turn the piano on its side for moving. No destructive features are involved, and nothing touches the piano except plastic zip-ties. No holes are drilled, and if the unit is removed, the piano is restored to its previous state. Installation is not much more time-consuming than the regular units, but these models are sized exactly to the piano they are intended to be used on, and we require either the make and model (for example, Yamaha C-7) or some measurements anyone can take.
