I've been seeing a lot about this thing called an O-Port and the claims are pretty effin' bold, saying it will take a lower-end guitar and make it sound top shelf for $20. Where exactly does it attach to the guitar? What exactly is it? And is it half as awesome as claims make it out to be?
It has something to do with how it changes the projection of the sound coming out of the acoustic's hole. I thought about buying one for my acoustic to control feedback instead of getting a sound hole cover but I never got around to it.

Here's a link


I guess there is some logic to its design. Now whether or not it works, IDK.

Seems pretty cool I guess. I mean for 20 bucks if it makes a bit of difference I guess its worth it.
