Yesterday, (Jan 27, 2018), I discovered that a short, twisted segment of tape (3M Brand 600 tape, or 3M's "Gloss Finish Transparent Tape"), placed under the surface wave input tape on one of my "Tone Amps", (or the new, soon-to-be-announced "Butterfly Timbre Amps"), so that their adhesive layers of the two tapes are in contact, gives almost unbelievable volume, sustain and sound quality to the banjo! I just posted a sketch showing how to do this in my photos section. Players who use my "Movable Tone Amplifier" in their banjos should definitely try this new installation method. This new installation method will also be recommended for use with the new "Butterfly Timbre Amp", scheduled for announcement later this week..
The greatly increased performance from placing the two adhesive layers in contact is due to the physics principle of "Constructive Interference", which states that when waves of the same or similar frequencies meet coming from different directions, their amplitudes will add. The huge increase in performance from placing the tapes together with their adhesive layers in contact illustrates what I have long suspected. - That their sound surface waves travel most efficiently in their adhesive layers.
