Finally decided to try doing away with the ferrule on a couple of calls to see how I like it. Frankly, the ferrule isn't necessary the way I construct my trumpet yelpers, so I didn't do a ferrule on this one. The customer wanted Hawaiian Koa with nice figure, and I think the figure in this call satisfies that requirement. I like the picture I took in the shop better than the one I took outside. When you turn this call in a little light it changes colors. This is why I have a Koa addiction.........LOL!!!
