This spiral sphere creates the illusion of 3-D using fine relief cuts. This design offers heavy feedback reduction. This insert will fit most standard size guitars with a 3 7/8" to 4" inside diameter. The wood in the picture is maple. It is available in other woods. Wood color and grain can vary.
Lacuna Acoustic Art designer inserts are made from 3-ply quality woods. (apprx. 3/8" thickness) Each insert is fitted around the inside diameter with extra-resilient Poron Foam mounting pads. These hold the insert sturdy in place and safe against your acoustic guitar's soundhole finish.
