The Planet Waves O-Port’s material is custom blended for flexibility to prevent damage to your guitar finish and inlays. The O-Port suppresses feedback and gives your acoustic or acoustic-electric guitar a fuller sound with more volume, better clarity, and enhanced projection.
Just measure your acoustic guitar’s soundhole and choose the Planet Waves O-Port that fits best.
