OVERVIEW

An acoustic guitars sound enhancement port with no electrical parts.

This Planet Waves O-Port is proven to enhance the sound of any acoustic guitar and kill feedback without the use of electronics. It's has been tested under the scrutiny of world-renowned acoustic engineers and sound producers to improve tonal quality. The result is a fuller, richer sound with noticeably increased sustain and harmonic range. The tonal enhancement provided by the Planet Waves O-Port is particularly pronounced when the acoustic guitar is plugged in and amplified, resulting in a much fuller sound, a stronger signal to the internal pickup, and significant feedback control. The Planet Waves O-Port fits in most acoustic guitars with a round soundhole, regardless of make or model.

The Planet Waves O-Port's material is custom blended for flexibility to prevent damage to your guitar finish and inlays. The O-Port suppresses feedback and gives your acoustic or acoustic-electric guitar a fuller sound with more volume, better clarity, and enhanced projection.

Just measure your acoustic guitar's soundhole and choose the Planet Waves O-Port that fits best.

Small: 3.375" - 3.5"
Large: 3.875" - 4"

  • Non-electrical acoustic sound enhancement guitar accessory
  • Custom-blended, flexible material prevents damage to your guitar finish and inlays

Planet Waves O-Port Review

I play a Breedlove Atlas Series (jumbo body with maple back and sides) and I have always loved the sound of the guitar, but I have sometimes wished that I could lose some of the boomy bass. I bought the O-Port after seeing the display at a local music store. I installed it in my guitar and I am very impressed with the results. I see that a lot of other people have used words like "clarifies the sound" and "focuses the sound", and that is about right. With the O-Port installed, the sometimes intrusively boomy bass is tamed - especially plugged in. I also noticed that my acoustic volume seems to have increased, though some reviewers here have said they can't tell a difference in volume. My brother in law also has a Breedlove Atlas (dreadnaught with rosewood back and sides), and we play together when we get the chance. When I pulled out my guitar and hit two chords this weekend, he immediately noticed a difference in my volume and overall sound. I think that if you have a really nice guitar like an expensive Gibson, Martin, or Taylor you won't hear any difference in the sound. With the less expensive guitars, however, I am convinced that the O-Port makes a very noticeable improvement in the sound of an acoustic / acoustic-electric guitar. I think it's well worth the money, and I am going to pick one up for my Sigma-Martin that I've had since 1983 as well as my acoustic bass. Awesome Invention!!!
Not many features...it seems to hold its shape (round), and the lip that goes around the outside of the soundhole is sturdy.
I don't think I will see it destroyed in my lifetime unless the plastic gets brittle with age.
I think for what the O-Port did for my guitar it is an excellent value.

OK,let's me tell you how this works. The o-port reduces or eliminates some vibrations at certain frequency. As the result, (1) the volume becomes smaller significantly; (2) the bass becomes less boomy; (3) the clarity of the sound might be enhanced because some onvertones are gone, but I can't tell; (4) you can play harder to produce louder sound because the sound now is more "clear".

Now you know, it doesn't make the sound louder. It just makes it possible to play louder sound without noisy overtones. If you read the manual or description of the product carefully, you'll find that they never say it for sure that the volume will be enhanced by the o-port.

I installed and removed it. The hard plastic o-port caused paint around the soundhole peeled off a little. If you install and remove many times, you'll eventually see the permanent damage to the paint of your guitar. The o-port is not made of soft rubber. It's made of hard plastic.

Think twice before you buy. You'll spend more on the return shipping.

Comments about D'Addario Planet Waves O - Port:

Works great on guitars with low volume like mahogany. If you have a high quality spruce, cedar, or other high resonant tone wood that projects loudly, then it will actually subdue it. I tried it on 3 guitars- a Greg Bennett Samick mahogany, a Sky acoustic bass, and an Indiana S-Scout. Helped the Samick and Sky tremendously! These both had low acoustic volume. Also on the Sky bass, when it was amplified, it would feed back horribly- that problem is now nonexistent! So it does what it says. Now for the Indiana....it is the loudest acoustic guitar I've ever played and when I installed the O Port, it actually lowered the volume and the sound became muddy. So it all depends on the specific guitar- it helped the 2 that needed it.

Comments about D'Addario Planet Waves O - Port:

I ordered the O-Port for my "Mini Maton" guitar for improved amplification performance, and feed back control.It arrived promtly, and It fit well (with a minor cut for adjustment) the MATON guitar has a large block inside where neck mounts to body. The O-Port cut easily with scissors to custom fit inside and it slid right in and fit well. I instantly noticed improved tonal response in the mids and highs. It also improved projection and volume. It seems to work well in feedback supression.Remember to measure the sound hole O-Port comes in 2 sizes which will fit everything. Overall I am very pleased with the O-Port and Musicians Friend.

Best Uses

    Comments about D'Addario Planet Waves O - Port:

    I've installed this on my Washburn D26 (Solid Cedar Top with Laminated Koa Back and Sides) which has always been loud, but a bit boxy sounding. The installation was relatively simple and quick (A few minutes including loosening and retuning strings). It's a nice snug fit.

    I could immediately tell that the sound had improved. Notes really are more defined, clear, and have better sustain. The general timber seems to have also warmed as the guitar is now a bit more bassy and balanced even though the high strings seem brighter, yet fuller, too. Interesting thing, and I don't know if this is good or bad, it is almost impossible to overdrive the sound. No matter how hard I strum (with a medium-hard pick) there is a "volume ceiling." Where before, hitting the volume ceiling meant putting out a very harsh sound, now even with hard strumming, the guitar sounds as if it has been tamed a bit. Picking individual notes also produces a clearer tone.

    The only possible downside: I am a bit concerned about the material potentially damaging the finish and wood around the hole. As I will probably never remove the O-Port on this particular guitar, I'll never notice if any damage has occurred. It's also my beater, so who cares. I can't see myself installing one of these and taking the chance on my Taylor 815 or my Larrivee L9 - besides they don't need any help in the sound department anyway.

    In addition, I can't tell if there has been any effect on the plugged-in sound. Feedback, tone, sustain, etc. seem the same.

    Finally, my buddy put one on his Gibson Songwriter, but I don't think it's had similar effects. His guitar has definitely gotten quieter and is not the boomy and bassy guitar it once was. While the volume suppression has also taken place in his Gibson, it has done so much more significantly. Don't get me wrong, it still sounds great with the O-Port, but it has an entirely different personality. What was once a throaty guitar with strong attack, is now more of a crooner. He loves it. Me, not as much.

    A previous review had mentioned something about the O-Port having more positive effects on lower end guitars and not so much with the higher end ones. Maybe this is what he was talking about?

      Comments about D'Addario Planet Waves O - Port:

      I bought two: one for my steel-string dreadnought ('98 Martin DR), the other for my nylon-string classical guitar ('67 Guild Mark II).

      The difference it made on the Martin was marginal. The difference it made on the Guild was huge! So I think that maybe it works better on smaller bodied guitars.

      Hope this helps.

      I have used this device in 3 inexpensive guitars used for gigging.I find that it has added focus and projection to them and while possibly making them less boomy it definitely added focus and balance.

      not worth it

      Pros

        Cons

        • Difficult To Use
        • Not Functional

        Best Uses

          Comments about D'Addario Planet Waves O - Port:

          ok, first off I wanted a soundhole cover that not only improved sound live, but also controlled feedback. This device did neither. First, you have to loosen all your strings to place the unit in the soundhole and loosen all the strings to take it out. Second, the unit did change the sound some to be in my preference a little more midi, but overall it didn't change much. Third, the unit actually doesn't help with feedback. I played live with the unit the next day I got it, and I got massive feedback during practice. For sake of time I had to push the O-Port into the guitar and use the cheaper planet wave unit which worked wonders. Fourth, the unit depending on the guitar actually pushes against the electronics.(thats a cause of disaster.)
          So for the money not worth it and doesn't do what you want.

              There is a definite difference in the sound of my Seagull Maritime Mini-Jumbo (Spruce top /Mahogany sides & back). There is separation of notes, a clarity, especially when finger picking where I believe there is also a volume difference. Amazing how something so simple and inexpensive can make a difference. I will buy these for my other acoustics!

                      I got an O-Port because my acoustic bass guitar was feeding back, and it has greatly reduced feedback. Our sound guy gave it the thumbs-up. Easy to install, and it keeps the sound hole open. It's a keeper.

                          This is not for every guitar and doesn't produce a miracle in most cases. It does reduce feedback when your guitar is plugged - not a miracle but a BIG DEAL ! I put it on my cheap AC10 Esp and it makes it sound great. On the Martin D35 it didn't do as well as it sounds great at all times. Want to reduce feedback - get one - want to take the harshness out of a price point acoustic - GET IT - want to put one on a good Taylor or Martin - Shame on you ! LOL
