I’ve made several four string banjos in the last few years, but most have been tuned dgbe, like a baritone ukulele. This one is going to a tenor banjo player though, so he needs cgda. This tuning, combined with non steel strings, a brass tone ring and a walnut block rim gives an awesome sound. Loud, but rich and funky too. The curly walnut is from The Dee Mill and the pistachio is from California orchards. The fancy brass hardware is from Brooks Masten.
