Planet Waves O-Port Large

A friend needed an increase in projection from his 20 year old beater so I bought one.
In short, it works. There was more pronounced bass and a very noticeable increase in projection.

I just installed one in my Taylor. I love the results. A little more volume also. Thinking of getting another one for my Martin.

To keep it short and sweet - a more balanced tone with a moderate increase in volume. Easy to install, and I am very happy with the results.

i've had a a beatiful concert size breedlove for nearly 15+yrs. had the cedar top replaced 5 yrs ago.did not think it would ever have much bottom. this little gadget either works great or has a placebo effect that should be bottled and sold.either way i could not be happier w/the sounds and tone this device has helped me achieve

I installed o-port in my carvin acoustic electric. More balanced tone, slight increase in volume unplugged. When amped, I had to dramatically change EQ. Overall satisfaction, but a royal pain in the butt to change battery in the Fishman.

I purchased two large and one small O-Ports. I gave one of the large ones away as a gift. I put the other large one on my Martin D35. I am getting a little more volume out of it and the bass stings sound bassier and the treble ones sound more treble. There seems to be more separation of the string sounds. I like the sounds that the O-Port is helping my guitar produce.

I put the small O-Port on my Yamaha nylon string folk guitar. Now , there is a very pronounced improvement in the sounds coming out of that guitar. The improvement is more evident and noticeable than on the Martin.

At $20 per O-Port, it's an inexpensive way to upgrade.

Have it installed in my Epiphone EJ 160E (John Lennon model) and wow, what a difference it made! The bass is lot more solid, both mid & treble much clearer! Just ordered another one for my 'Washburn' ..... will wait and see.

This thing rocks! Much more volume, bass and better tone! One of the best investments! I couldn't recommend it more!

O-Port - fine product
February 11, 2011
I received my O-Port from Just Strings.com packed well and ahead of schedule. I installed it on my Cort MR710 maple acoustic, and got what I expected: more volume, more bass, better balance. In short, it made this $500 guitar sound like a $1500 one. I'm very pleased!

Seems to work.

The O-port makes my Jasmine dreadnought sound much fuller and rounder. It also seems to be a bit louder.
