Our new Movable, Tunable Tone Amplifier For All Banjos replaces all previous models of tone amps because of its superior performance. The difference is that it has three separate audible sound generating planes separated by two bend lines.(see photo). By bending the tone amp along the bend lines the player can easily adjust audible sound outputs to intersect and so amplify. This tuning capability gives the player the ability to selectively increase the volume of lows and highs and improve sound volume, quality and balance for his or her particular banjo. For example, for our Gibson Mastertone tenor banjo the best sound resulted when the low frequency plane (with the two staples) was bent up 90-degrees and the high frequency plane (with the steel tone piece) was bent up 30-degrees. Please note the new photo which shows the tone amp taped to the wood rim at an angle of about 45-degrees. This taping at an angle to the input sound surface waves (on the wood rim) results in a very large increase in sound quality and volume from the tone amp. The reason for this vastly improved performance is explained in detail in the second blog entry of October 9, 2017 on the "Reviews and Blog " page on our website. Customers should make this easy change immediately because the improved performance from the banjo is truly amazing. The "Travel Caddy" holder is included with your purchase of the Tone Amp. The "Optional Tone Piece Set" (shown above) is $6 USD extra.
