The WA web site states there is an audible change with pianos. I would put it on the piano's soundboard. Professional drummer Drew Hubbard just tried the chip on his drum set- tom-tom an audible change, the kick drum -no change.
Also interesting is the effect of Synergistic Research's Quantum Tunneling. There is a significant change to the sound of acoustic instruments when their strings are treated. I have heard the change on cello strings, viola strings, and Fender Strarocaster electric guitar strings..
