I used this to replace a scratched up and plain black pick guard on my wasburn Lyon full size acoustic.I noticed many reviews said this was cheap and thin, but it's the same thickness as the one I removed. And it looks fantastic.I removed the old one by carefully pealing it up, then used goo off and a guitar pick to scrape off the glue. I lined this up, out some masking tape down to show the positioning, the carefully laid it.The circle size matched the center abalone ring around my sound hole. Sure, I wish I didn't cover the abalone, but no big deal. Exactly where it goes will vary from guitar to guitar.When done I peaked off the protective coating. Easy peazy.You can see a tiny bit of the lighter color of the body as this isn't. Perfect fit, but it's an old guitar so good enough. I'm super happy!
