A little while ago I received a Planet Waves O-Port in the mail from the kind folks over at D'Addario. I was eager to install it on my acoustic guitar, as it promised to improve both the quality and quantity of sound that comes out of it.
Installing the O-Port is a fairly simple process, you just take the strings off, bend the rubbery O-Port in half, put it into the sound hole, let it pop back out into full shape, and then adjust the positioning to where you want it. Put your strings back on, and you're all set.
You'll see exactly what I mean in the video below, and although I did cut out a bit of the video (just the string winding and stuff) for the sake of time, it really doesn't take long to install the Planet Waves O-Port.
Once installed, I can personally say I do notice a big difference in the tone of the guitar. I don't know how well that translated onto this video, and of course the sound you hear is dependent on the speakers you're using as well.
What I can tell you is I didn't modify or edit the before and after sound at all, what I played is what you get. I also used a good quality microphone, though my position relative to the microphone changes a tiny bit, and that can really affect the sound as well.
Regardless of how well the difference in sound comes through on the video, I can tell you that when playing the guitar, I definitely notice a difference. In fact, I can feel the difference; the body seems to resonate a bit more than before. I really notice a lot more response in the lowest frequencies, and in general the guitar has a cleaner, less muddy sound to it. It's a bit hard to describe, but it is definitely there.
