This very simple and inexpensive bass note amplifier and sound enhancer is recommended for use with our other amplifiers and also when used by itself. It attaches to the inside bottom of the banjo's wood rim with two Velcro dot pairs and a 1-1/4 inch strip of clear acrylic tape (provided). The tape brings amplified sound surface waves to the device from near the bottom of the wood rim at a 45-degree angle. The device itself is a low frequency amplifier with a high frequency amplifier attached to its top surface so that their audible sound outputs mix less than an inch below the head of the banjo. It is believed that this close proximity to the banjo head essentially makes the head a functioning part of the amplifying system and that this is a reason for the incredible volume and sustain delivered by the device. Sound quality is probably also improved because the high frequency amplifier amplifies the harmonics of the low frequency notes making them rich and beautiful, and, aided by the banjo head, probably does the same for higher frequency notes. Four sound surface wave amplifying steel staples are used to amplify and control the flow of sound surface waves through the device. A "Theory and Instructions" document of 2 pages can be downloaded free from our website (see link elsewhere in this ad) and provides more detailed information including photos and the side view drawing shown here.

Recently, a new player asked me in an email which of our amplifiers he should purchase for his inexpensive banjo. After thinking about it and remembering my own first banjo I recommended this Bass and Enhancer amp. Because it is like two amplifiers in one since it has a high frequency amplifier on top of a low frequency amplifier, and they both work great. It's also easy to install, stable in the banjo and, because it is easier to construct, cost less than our other amplifier/enhancers.

The non-sticky red tab on the drawing of this and other amplifiers has been eliminated because we learned that it was degrading the sound. Instead of the tab we now fold over a corner of the end of the input tape which makes it easy to move without degrading the sound..

Some banjos have rim bolts which are spaced closer than the width of the Bass Amplifier, forcing the Bass Amplifier to be installed on top of the head of one rim bolt. When we expressed concern about this a customer with such a banjo reported that placement on top of the rim bolt did not cause a problem and he ordered a second one for his other banjo.
