For ACOUSTIC ELECTRIC GUITAR

Low end rumble, howling mids or screaming highs ruining your electric/acoustic guitar sound then this Rubber sound hole insert is for you.
Simply slip the easily mounted insert under the strings and into the sound hole.
This effectively minimizes annoying resonant frequencies interfering with sound of your bridge mounted piezo pickup system. Want to convert back to full acoustic sound , no problem simply slip the insert out.
