Best 12 String Guitar Tuning App

Best guitar interface

Just starting with guitar. Purchased this to assist with tuning. Easy to use, easy to tune.

This was part of the package for the GL1 Guitalele - Nylon-String Guitar Ukulele (Natural) by Yamaha. It was all given as a gift and well received!

My first nylon string guitar of this type and I'm absolutely amazed at how nice this is. It's a very light yet solidly built guitar. Fit and finish is stunning. Playability is easily comparable to guitars of this type that are more than twice the price. Very pleased with this guitar.

Works very well on my Cordoba nylon string classical guitar. Firm pressure, grip is effective but doesn't damage anything. Easy to use.

I'm a jazz guitarist playing an 8-string classical guitar that goes higher and lower than a regular guitar. It has a K & K pickup and I my amp is a JBL EON powered speaker, which, for this instrument sounds better than any jazz guitar amp. I have used the Zoom A-3 preamp as well as an L.R. Baggs Venue DI. They are both very good but I'd say the Grace Alix is the best I've found. It has great features you can read about but I must say that the sound of my guitar with the EQ set flat is strong, clear and simply amazing! It's very well thought out. Worth the price.

Accurate, precise guitar tuning without a lot of confusing modes.  And the on/off switch is on the front which is nice.

A great inconspicuous tuner. Easy for you to see and nobody else. A must for a 12 string. No excuse for not being in tune. I’ve got six of them.

[This review was collected as part of a promotion.] Great Sound but tuned different for this particular set, so tuning in the app is highly recommend to get it’s best, being able to control all settings in the case without unlocking your phone is a plus.

Extremely satisfied with this speaker. Sounds great, has substantial volume, bass and treble with all frequencies in between. I am using it in my side-by-side UTV with a velcro bar mount on the roof roll cage while I'm out plowing snow, and have no issues with volume, or connectivity. The only improvements I could potentially think of is maybe a way to manually select/override the position audio tuning in the app, or an in app equalizer. Since I mount this with the main grill facing almost down, I'm not sure which audio tuning it is using, and might not actually be get the most out of this feature, or the best sound for my application. But again, it still sounds great, just like every other Bose product I own, and I do have quite a few products, old and new.
