This is a 2 string slide guitar that I started making forever ago, but just recently finished. It is mostly just scrap wood and a cookie tin. The frets are yet to come. I used a sawed off bolt for the nut and a piece of bic pen for the bridge. I used the third and fourth strings from a guitar. It is not in tune at all in the video, and I have no idea how to play slide guitarQ. I put in bolts so it could be held with a guitar strap, and eventually I want to get a piezzo into the tin and make it electric. It doesn't sound all that good, but its not the wourst I have made.... And yes I am using an Altoids tin for a slide. The strings are just put through a hole in the bottom of the tin.
