The Diddley Board Two stringed washboard guitar

My latest build, made in 1898 this old washboard s got a new life as a guitar Just two fat strings and a whole lotta thunderous bass, seems like a perfect instrument for Geezer Butler, haha I often play my diddleybow CBG s on my gigs and now I can add some bass to that single string blues The DiddleyBoss. .; )
