Just ordered a new slide from Taylor guitars. It's made from ebony. It's super light in weight and won't fret out on a guitar that's not set up for slide. Mine is 11/16" in diameter, however they offer different diameters for whatever size you need. Cool that they are made from scap and are of high grade scrap at that! Less waste is a good ideal. Will post pics when it arrives along with a review of how it sounds. Expecting that it will not be very warm or long on sustain, but a cool piece to add to the collection.
