John Redstone was rehabbing The Old Dog Saloon in Finster, Wyoming. He found this behind some double thick sheet rock in what had originally been the ladies' room. It had an unreadable note taped to the strings and a diagram of how to wire up the red button marked R below the tone knob. Both come with the purchase. Brown stain on back probably isn't blood. This guitar might be Fat Jelly Marburn's "Big Green". Let's hope not.
