Quality of the Feedback Eliminator for 808 is good. It's ticker then Feedback busters for Yamaha guitars for example.
The problem is, it does not fit the whole of Maton EBG808C TE model. It partaly goes into the whole, but cannot go all way in. Trying to push it a bit, I just damaged edge of the sound hole on the guitar (which is still very new).
Not sure what the issue is here, if product is not labeled correctly, or it is production issue from Maton, but it's not working as intended.
