New High and Low Frequency Dual Surface Acoustic Wave Mechanical Amplifier Pair

Posted by yellowdog on Friday, March 22, 2019

I recently invented a pair of high and low frequency mechanical amplifiers and sound quality enhancers for all banjos which will eventually be offered for sale on BHO.  It is, by far, the best device that I have invented to improve the sound of banjos, and work is continuing on a version that works on acoustic guitars.  The two amplifiers are taped, side by side, to the inside surface of a banjo's rim and are easily moved about for maximum performance.

Excellent five string player and "Banjo Newsletter" regular contributor ("Earls Way"), Bob Piekiel, will be using it in his banjo in a banjo jam the Greater Nashville area on March 25, 2019, and I will be performing with it in a gig in the Atlanta area in my Gibson tenor on March 29, 2019.  We expect that it will "knock the socks off" both audiences!

If that happens look for my BHO ad soon offering them for sale.  You can also easily make your own because dimensioned drawings and an explanation of how they work are already posted on my website, GeigerAcousticDevices.com.
