This is a cool little product. I really like it for my 12-string acoustic guitar. The good: easy to use. So many alternate tunings. Can be used with any stringed instrument. It is accurate. I don't know if it is perfect, but I compared it to my headstock tuner, and 3 of the strings are dead on, and 3 are just a little bit off. I don't know which tuner is wrong, and which is right, but they are incredibly close, and my ear can't tell the difference. Having a metronome included is cool. The Bad: It is a little awkward to use on the G,B, and E strings on guitars with headstocks with 3 pegs on either side of the headstock. G is the hardest to do, but you get used to it. I doubt there is any way they can improve that, so it isn't really a big negative for me. I haven't used the feature yet, but I think where this thing really pays for itself is alternate tuning. It doesn't require a lot of thought to quickly get to an alternate tuning. It does require some initial programming, but the menu is pretty intuitive, so not an issue. I haven't used the winding feature yet either, but I am sure that will be my favorite feature. The metronome is cool. I have only used it once, but I sat it on the stand next to me, and the vibration feature made it spin in a circle. I was afraid it was going to fall off the stand, but it just sat there and spun around. all in all, excellent product.

Tuning up a guitar in the back of a dark bar can be a pain, often i found that clip on tuners like snark can vary greatly. With the R3 You can select your instrument, key, and then position the tuner on the peg and hit the string-- it will wind your string and do micro adjustments till you feel a buzz, go to next string and repeat- very fast. can also do other instruments like mandolin etc. just make sure you hold it firmly when tuning. Spot on for me. also has a winder feature for changing strings, and a metronome. very handy little device, been using it for gigs for 6 months now and works very well!

This was my first experience with an automatic tuner... and I LOVE IT! Yes, it's has its issues... like, for example, if you pluck the low E string and the tuner adjusts your tension - if the tuner thinks the E string is set and ready to go, it moves on to the next string. So DON'T TRY TO DO A DOUBLE CHECK of the string you just tuned. Because if you do, you're going to pluck the E string again and it's going to have moved up to the A and it's going to try to tune your E string up to A. It's better to just keep going... never double check a string until after you're done tuning all 6 strings. Then, and only then, you can turn the unit off and then double check the individual string tuning. More often than not, however, I find the strings that I wanted to double check to be just fine and fully in tune with the rest of the strings. It's a very nice unit!!! I personally love it.

I bought this out of curiosity and tried it. Thought is was not very good as a tuner and tossed it in a drawer and forgot about it. Fast forward and I found it again. Thought I would update its software and try it again. It still is a pretty lousy tuner. I mean how incapable do you have to be to not tune more accurately than this. But where it IS useful is on your guitar work table. It is about the smallest power winder there is and it saves space. When working on guitars you often have to string and de-string guitars when working on nuts, saddles, bridges, fretwork, etc. This functions as a power winder and allows you to tension strings “close enough” to be near pitch so you can check the fit and results of your work. It still is a lousy tuner for accuracy but it is a handy workbench tool.

Bought to help quickly tune my 12 string Taylor at gigs. It takes longer than expected to tune and isn't very accurate, even when I do it a second time. Winding/unwinding feature does work fairly well. I continued to try using it beyond the date I could return it because I hoped I could get it to meet my needs. If I could, I would return it because it is not the convenience I thought it would be. It is faster and more accurate to use my pedal tuner.
