The O-Port™ by Planet Waves will make any guitar from beginner to custom-sound richer, fuller, and louder, with more clarity and better projection. The Planet Waves O-Port material is custom blended for flexibility to prevent damage to your guitar finish and inlays. Your O-Port will suppress feedback and give your acoustic or acoustic electric guitar a fuller sound with more volume, better clarity and enhanced projection.
