I think this applies to this thread

Gunna see it tomorrow, I just want an idea.
I have a Martin but it's just electric. Will this still improve my sound? Just wondering

I never need an acoustic electric cbecause it's either not needed or I am miced already. Oh and wouldthis work with a pick up thatyou just place over the soundhole? I have one if ever necessary =]
not sure but i think this goes inside the guitar so i doubt it would work on your electric
No. Its for putting in the soundhole of an acoustic to stop feedback from monitor speakers. It wont do a thing for a solid body or even semi hollow electric guitar.
So it won't do anything for the tone/sound of an acoustic guitar that's just played acoustically and not plugged in?
