Thanks again 'Spaw. I thought I would hear from you eventually on this one.This from Bill Palmer's site.
The EMERSON "Power Bridge" Approaching a Stelling sound on a Gibson banjo
The other bridge that I received was a bridge from Kelly Emerson. Kelly is the son of Bill Emerson, who is a remarkable banjo player. Bill's "Banjo Jamboree" is one of the fastest banjo instrumentals I have ever heard.
I was on an auction site and saw these banjo bridges advertised, so I e-mailed Kelly about them and he sent one to me to try out. I thought the claims he made might have been a little excessive--until I tried it. This is a really fine bridge!
It is made of cherry wood--no ebony top--it doesn't need one. This bridge really kicks up the volume of a banjo, with particular emphasis on the treble end. However, you don't sacrifice any bass for it. I have tried this on several banjos and I found it quite interesting. Unlike most bridges that simply make a clacking sound when they are dropped, these bridges have a definite pitch. They go "clink" when dropped onto a hard surface.
I found that my Scruggs model had more bite and volume when I used this bridge on it. If your banjo needs a boost, try one. You can order them from Kelly Emerson at Banjo Fever.com.
