Korg GA-40 Large Display Guitar and Bass Tuner



The GA-40 is a dedicated, easy-to-operate guitar/bass tuner with automatic pitch detection. In Guitar mode it supports seven-string guitars (7B through 1E), and in Bass mode it supports six-string basses (Low-B and Hi-C). With the precision you expect from KORG, the GA-40 indicates the pitch quickly and accurately. The LCD needle-style display provides both the accuracy of an LCD as well as the easy viewing of a needle indicator, and the display has been enlarged for even better visibility. You can also use the built-in high-sensitivity microphone to tune an acoustic guitar.

Review by R. Sherling from Schenectady, N.Y. USA:

I enjoy this thoroughly. No problems, comes with tuning chart so you can see what you have to tune it to, and it auto-detects the note played and then tells you if you're to sharp or flat.

Review by Rick "Fourstrings" Lauzon from Lehigh Acres,FL.:

Having played for many years, and I can't stand to hear an instrument out of tune (usually flat).
I learned right away how to tune guitars "sans-equiptment". I was used to playing Blues and Rock in the 1950-s and 1960's in the key of "E" and most three chord songs were in that key, while some drifted into a "C"..I got used to tuning in "E" and hearing it when it wasn't there, as it is the first top string on guitars, and Basses which gave me a fit, (the bass).
I recall that many guys I played with always took like a good 1/2 hour pinching their keys and saying "wait"~!
I would get a good "E" on the top then go down the strings remembering that the "B" string was flat 1/2 step, and got used to it.
But, I always waited for these key - pinching fanatics, until I bought my first Bass, then I asked all for a Bass or low "E" chord then went from there..it was my system and was great for me, as the Bass "E" was nearly impossible to find all by yourself,(bass) there are no forks in the "E" (low) key.
I bought my first KORG-30, and Korg-60 for my Mandolin and guitars and basses.
I found most to be off including me!These Korgs will put you in the ballpark, then there are your "key-pinchers" always with an issue on tuning!
Wasting time for practice and playing for audiences, this was always great enough, but, the Korgs and others I had bought were not in agreement, as others were flat, and Korgs even of the same Item # disagreed.
This would be true even if all had tuned to an organ or Harmonica or pitch pipe, but the Korgs, even though not always agreeing w/ one another, would certainly disagree with other makes, so, if one is to complain about a few "Mc-steps" in pitch, be cool, as the ears are not going to pick up these micro-pitches that are picked up and disagreed with by other means.
These are a great invention and puts you there, in spite of the fact that my Amp has a built in Bass Tuner, that I am always checking when I practice or play.
So, I'd rather be off tune by less than a "key pinch" and use these Korgs or ANY good Name Tuner..Don't leave home w.o. it.
Keep one in your pocket, your case, your amp. top, strapped across your forehead like a "Samurai Warrier" (With the letter "E" across the front center)!.
It is the best we will have for a while, but we all will start on our bosses time schedule, and play w.o. the "key-pincher's amp "off",when not in sight.~!~!~! (He/she will always disagree anyway).

Review by Eric from Albany, NY:

This is a great device that makes tuning a guitar fool-proof. Easy to use, easy to read, and accurate.

Review by Greg Beaver from :

Good tuner, but it has trouble discerning some strings from each other, even when the guitar is properly tuned. This may be normal with guitar tuners, as this is the first one I've ever owned. Other than that, it's a good, cheap tuner that gets the job done, but probably not the best choice for a professional player.

Korg GA-40 Large Display Guitar and Bass Tuner

This tuner is great! I bought it to tune my Ibanez BTB200 Bass. Everything about this tuner is truly A+. If there were any negative things to say about it, I'd have to say that the little flip out tab in the back to make it stand upright is a bit flimsy. Also, the tuner's mic can be a bit sensitive. It just makes tuning it sometimes a bit tedious. But it is spot on accurate! My bandmate has used a Boss tuner for a long time and he, too, was amazed by the accuracy of this tuner, not to mention the price! Other than those two extremely small issues, I love it!
