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.

Well, I wanted good quality tuner for my studio. This one does not tune correctly - so there is not much to say about it more. There is better tuner out there that most people including me are afraid to use - OUR EARS. I tuned my guitars for half of my life (I'm 51 now) using my ears and I was fine. The minute I started using tuners - I have problems with tuning.... LOL

                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!
