Enter to win the O-Port while supplies last! The O-Port is designed to make any guitar from beginner to custom sound richer, fuller, and louder, with more clarity and better projection. The 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. It’s easy to install. Simply loosen or remove your guitar’s strings and fit the O-Port into its soundhole.
