great tuner

Easy to read and easy to use as well as very accurate. I love this tuner.

Done with Clip-on Guitar Tuners

I have owned this for about a year. Frustrated after years of fooling with finicky headstock tuners and their micro batteries I had to find a better option. The display is great and standard AAA batteries is a huge plus.

Korg GA Custom tuner

Have had this tuner for about 1.5 years now and it is the best for the money. I checked it with my Sonic Research Turbo Strobe tuner ST-100 and its right on the money. I plug it into my tuner out on the amp and it is visible in the dark.

a great replacement / backup or main tuner

my two main tuners are a Korg Pitchblack pedal on my pedal board, which operates much in the same way as this one (the display is a little less fancy and more functional), and a very old Korg GA-12. I also had two very old 9v powered GA tuners with the monochrome LCD displays that have since been given away to others in need of tuners.

Korg tuners have always been reliable for me. My GA-12 is showing its age though, and I'm not sure how many more outings it will survive, so this is technically a replacement for it. The GA-12 itself is very similar to the current orchestra model, with the ability to select several different instruments-specific modes (guitar in std and tunings, bass, ukulele) and manual modes. it also has a pitch generator for tuning by ear.

This tuner is more compact, has a bigger and clearer display, easier to use, and is technically more accurate. It lacks instrument-specific modes but doesn't really need them. It also lacks a pitch generator but i bought a chromatic pitch pipe for that, which i like better because it isn't dependent on battery power.

I love that Korg chose to power it with readily available AAA batteries, which lets me use rechargeables.

For the price, i can't think of a better tuner on the market. I hate those little clip on tuners for a couple reasons, but if you want that sort of thing, Korg offers a clip on contact mic that gives you the same functionality in what is for me a more manageable and practical form factor.

IMO, Korg nailed the features, functions and price points on this, and I've loved every tuner of theirs i have had. This one is no exception. I'm not impressed with polyphonic tuning, and don't see anything super exciting from others that Korg doesn't already do well. I expect many years of good use out of this thing!

Best Handheld Tuner

Easy to see, share, store, and use. Used it church band, and it became popular, because even an acoustic could use it, and storing it in a drawer is easy. Supper accurate came in handy with picky, golden earned band leaders. Use it to practice at home with multiple instruments.
