This tuner is extremely accurate. For many years I used a cheap tuner that would never settle and constantly jump around when trying to tune my guitar. This tuner does not jump around at all even when tuning low.

I bought this tuner to use in my studio. After one year, it malfuctioned. Try getting anything back from Boss. A VERY high priced tuner for what you get. I bought a korg yaers ago for the road, and it is now in the place of the Boss. I`ll pick up another Korg for the road. I am really unhappy with this tuner and Boss. Their quality has been going down hill for years, and they seem to be making a good living off their former reputation. I`d skip this product and save some bucks in the long run.

            Comments about Boss TU-12EX Chromatic Tuner for Guitar & Bass:

            I ordered the Boss TU-12EX to replace the TU-12H I've used for thirty years. Although a little thinner than the older model it is just a touch taller so I had to enlarge the space a little in my old Boss pedal box, not a problem with a Dremel. I like the fact that the needle is adjustable without taking the thing apart like the old one, good to know if it ever gets off. Also, cents are marked every 2 cents instead of every 5 cents which might be useful. I've never used some of the features like flat tuning, or the audible tone; just need a reliable, accurate tuner. And I like these instead of the Boss pedal tuner because I can always take it out of my pedal box, put a battery in it and use it for acoustic instruments with the mic when needed.

                          very easy to use and accurate, has some nice features which i won't use but at least they are there. Nice backlit screen, VU meter is the ticket. Stage is typically too noisy to hear the beep when it's in tune, but I don't need that anyway.

                          I have tried several tuners - I prefer this one over the other two that I have (Behringer TU300 and Yamaha YT150}. In fact, I gave the Yamaha away.
                          I have been a big fan of the Behringer line (most all my effects are) but have been slowly moving away case in point, the tuner being reviewed!

                          I was trying to find the Boss TU-15 Chromatic tuner (no longer available it seems) and thought I`d give this a try. The older unit had a display light(with on/off switch)and some preset open tuning settings but this is a solid tuner and still has the two red tuning arrows as well as VU meter style display and the flat tuning feature.
