The Maton Feedback Buster 808 is the solution for every Maton players with 95mm hole.
Just plug it in the sound hole and you are ready to play live without feedback. You can play with stage monitors near you and drive your guitar like a ferrari.
It doesn't require any hardware changes and you can strum the guitar without the feedback buster poping out. Of course, if you have a Maton guitar, i recommend this Feedback Buster because it's made by Maton and you can have the same brand of the guitar in the feedback buster.
It's a solid and manageable black plastic for your guitar, it desserves to have the most clear and acoustic sound without any feedbacks comming from amps, stage monitors, microfones, etc.
