Information about Guitar Soundhole Feedback Blocker
The TGI Feedback Blocker has been specially designed to help eliminate unwanted feedback when amplifying your electro acoustic guitar. Simply insert the Feedback Blocker into your guitar's soundhole to regain control of your acoustic guitar on stage. The TGI Feedback Blocker also has the added benefit of allowing control of how much acoustic volume your guitar still produces. By removing the Feedback Blocker, turning it over and gently turning the internal "sound gate" located on the back, you can choose between a totally closed or partially open setting.
