This guitar has always had a great mid and upper ranges but the bass has never been "Martin" boomer, something I missed when flat-picking.
Put the O-Port in and the difference is remarkable.
A deep, clean, balanced bass to go along with the same clean, balanced mid and upper ranges.
I also added Power Pins (also reviewed) and the combo utterly transformed this fine guitar: Crystal clean through all registers, all the way up the neck.
The sustain had always been good, but with the power pins and O-Port, sustain is almost like a piano.
I cannot recommend these two items any more highly.
Let me say, though, I did get the O-Port for my Guild Arched Back maple bodied 12 string, but it's about a 1/4" too small, diameter. Ordered and received "large" for both.
Check your sound hole diameter before you order.
I also put an O-Port in my Cordoba Guilele (tiny little 6-string uke, basically). It took a little modification to get it to fit, but it cuts pretty easily with scissors, and eventually I got the shape and size right. The Guilele was the real proof that this thing works. It's a small, quiet instrument, with a top that might be too thick for the instrument's size, leaving it sounding a little dull. After putting the O-Port in, it actually has some projection, and can be heard throughout a room, and the strings now sound crystal clear.
All in all, I definitely recommend O-Ports. Nuff said.
I like to with fingerstyle and am going for a folk type sound, so I'm not hammering the strings with a pick.
I decided for the price, I would give the o-port a try, and I'm so glad I did. I chose the small size in ivory to complement my pink sunburst guitar. The sound hole measurement was the smallest option.
Installation was easy. I loosened the strings (without a capo as the video suggests) and just spread them to the sides for installation vs. pulling the bridge pins. It took some serious folding/squeezing and manipulation to get it in to the sound hole. The ring is much larger than the hole, so that extra material has to go somewhere to get it in. The piece is malleable plastic as described, but it has a rigidity to it as well. I got it in just fine, but then had to use a thin tool (smooth end of nail clipper lever) to coax the part of the o-port that lacks a rim out of the guitar to fit along the inner edge of the top of the sound hole. At first it kind of folded to the inside, and since there isn't a lip on that part, it stayed in until coaxed out. I wasn't sure at first, but then I remembered it's job is to smooth out the interior of the guitar, and if there is a ripple of any kind it can't do that as well, so I worked it out. It fits very snugly, I am glad I don't have any plans to remove it because I believe it would be a challenge. It fits very snugly into the sound hole, and would be hard to find a edge to lift.
The final step was to tighten and tune the strings. Total installation time was around 5 minutes.
Once installed, I immediately noticed a change in the sound. So did my children, and they aren't musicians. The guitar sounds richer and fuller as described. The thin tinny quality I sometimes had seems to be replaced by tones and harmonics that are much more pleasing to hear. The guitar is also louder. I don't have to play as hard to get a louder sound.
Overall, I feel like my guitar just got an upgrade. I don't plan to gig with this guitar, but I love how it sounds now. For all of you who have a smaller sized instrument, consider an o-port if you want a passive, inexpensive way to improve and amplify your sound.
FWIW I'm currently using Martin Silk n' Steel strings.
Two weeks later, and a friend who had heard the Daisy Rock before the o-port heard it for the first time with the o-port. They didn't know what changed, but noticed the guitar sounded much nicer.
Feedback is definitely reduced...not as much as a full sound hole cover, but it is certainly more manageable.
