The guitar is louder and the bass response seems better/clear

Let me put it this way a friend of mine brought his 5000.00 Taylor to my house to gloat and supposedly show me how a great guitar sounds

The O-Port is touted as making "any guitar from beginner to custom sound richer, fuller, and louder, with more clarity and better projection

The guitar is also louder.

If you can't afford a better guitar, may be worth a try

I read that the O-Port is best used to significantly improve a low-end guitar

I think this thing works, especially for a cheap guitar with laminate vs all wood body.

Probably would be more effective on a cheaper guitar.

" your guitar's sound hole dimension falls within the products parameter.

For a couple years I had been wanting to get a nicer guitar but didn't want to spend the money.

The O-port makes low-end and mid-range guitars sound like expensive guitars!

It won't make a cheap guitar sound like a Gibson or Taylor, but it does improve the projection some.

I wondered how could this improve that great guitar's sound?

This guitar is now a joy to play!

The guitar that I used the O-Port on is a good classical guitar to start with, and after installation it sounds worse, thinning the sound of the trebles

I play a $99 regal acoustic guitar.

an already loud guitar).Have already recommended (and gifted) it to several other musicians.

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

worthless thing, go invest in a good sounding guitar and u wont need it.

I chose the small size in ivory to complement my pink sunburst guitar.

It didn't make this US$300 guitar sound like a handmade Martin or a (more than 10X-the-price

An O-Port can help a guitar that needs help - a small body or cheap guitar

Definitely recommend for cheaper guitar

The guitar sounds incredible now.

An acoustic guitar booster for a reasonable price that can really make a regular acoustic guitar sound like a more expensive one it also sounds like equalization is increasing the brightness and bass notes too,Remember a large o port means a standard size acoustic and a small o port means usually the size of a flamenco guitar, I own one of each also its good to know this is a daddario product that make quality products like strings too!!!

For a couple years I had been wanting to get a nicer guitar but didn't want to spend the money.

It made my cheaper - not so great sounding guitar and changed the sound into a richer more full sound

This is an inexpensive beginner guitar

Don't get this and expect it to turn and cheap guitar with old strings into a booming Martin or

It won't make a cheap guitar sound like a Gibson or Taylor, but it does improve the projection some.

I have two guitars a Luna Guitar and a more inexpensive guitar

It amplifies the range as a whole too, it makes the lesser quality of my cheap guitar sound more like the better quality of my more expensive guitar

But when he removed it, it damaged the guitar, pulling paint and wood lose.

I suspect that this product would be even more effective on less expensive guitars

Honestly I think it will actually be standard in most guitars and might even change the way modern guitars are built

If you can't afford a better guitar, may be worth a try

ok i put this in my Yamaha guitar which it cost about 400 bucks and it made the guitar sound worse like it hushed its sound

The o-port doesn't enhance volume much and I prefer a quieter guitar for singing unplugged.

I play a $99 regal acoustic guitar.

Fingerpicking just does not sound as nice as before, even though the guitar is noticeably better on the bass notes

If product wasn't damaged at the time of arrival I would've tried to get this in but didn't want to damage my guitar or handle a damaged product.

Seriously, this is a hard brittle plastic that I wouldn't want anywhere NEAR even a cheap guitar, let alone one of my nice acoustics

I tried the O-Port on an expensive, show guitar, my Blueridge BR180CE

I now play it as much as my more expensive guitars.

Even he and his dad said that the guitar sounded good

They didn't know what changed, but noticed the guitar sounded much nicer.

I wouldn't expect this thing to make your "First Act" guitar to sound like a Martin, but it will make it sound better

My guitar sounded worse with it, less projection and tone

However, I was using the O Port on a 20 year old Taylor, so it's already a great sounding guitar

The overall view is that for cheaper guitars this works well, however the benefits drop off the higher in price guitar you go

When recording acoustic guitars with external mics I work at lower volumes and only get feedback if I accidentally leave my monitor speakers on

I used the large on an Aria Tenor and was quite surprised that a small guitar with a granted narrow range, could sound so good

Overall, I feel like my guitar just got an upgrade.

The guitar sounds incredible now.

Works great on those cheaper guitars.

My guitar's clarity improved noticeably

Not sure it really helped because multiple strings broke as I tried to re tightened them.
