Love My Little Korg !

From 2000 up to right before the end of 2013, I had a Korg GA-30 which was very dependable and had never let me down. I had only got rid of it because at the beginning of this year, I sold all of my electric gear and made the switch to Acoustic. I have 2 Acoustic Guitars , a 1999 Fender DG20S and a new, Fender CD60CE which I got from here and for a while, I was using Fender FT-004 headstock tuner which did the job but IMO, was not 100 % accurate. So a week ago, I decided to order one of these because I missed my old GA-30 and I wanted to see how good these were. Needless to say, this is one outstanding little tuner considering the price. My guitars now sound like they're accurate with their tuning and I for one could not be happier. Great product which I highly recommend.

Korg GA-1 tuner

It does the job and has all that drop tuning aid that helps you find what you really want. Its 7 string on the guitar by the way 6 string on the base 2 1/2 full steps drop in half steps, real cool. In a quiet room you can tune the acoustic no cord hookup needed. Can't beat it for the price. It also has a place to hook a lanyard. JDS..

Easy to use

God bless. Just used mine. Works best when plugged. Tuned my Bullet Strat with Mic. and when plugged in was off. Overall very nice for the price.

Don't buy this.

This product is a piece of ****. It will only tune 5 guitar strings, the low e string it does not pick up. So if you want a five string tuner go for it but if you want one that does all six strings then buy something else. What a disappointment.
