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.

Man if you have money to burn, this little guy is cool. Multiple profiles can be added. Multiple instruments. Pre-installed tunning settings (Drop steps, G Major, etc.). Hz change, Capo fret#, etc. Anyone looking at this has done some research (or should) based on the heavy price alone. Once purchased you can download and update the app and Roadie3. Customize your own tune settings via the app. I use it for personal use. So, I'm never in a rush. My settings are on the "Accuracy" and "Tune-up". "Fast tuning" that is sloppy on top of "Tuning-down" SHOULD NOT even be an option in my opinion. When and where would you ever require/want that combination? Makes no sense. Quick-tune it by ear if you don't care, and save yourself $150 bucks. Anyways... The only issue I have run into when tuning is that it will beep and stop working stating the error "On the wrong string" when I'm on the correct string. Has only done it a handful of times but can get kind of annoying. Works well with a noisy background. Does not seem to be any type of interference when using it. Has a re-string wind-up future, haven't used it yet but cool to have. I have only charged it once. Last pretty long for personal use, I'd say. If you were tuning a shop full of guitars every day plus re-stringing multi guitars every day and utilizing the metronome for a period of hours, your results may differ. The metronome future IMO could be cut from the chopping block. I would rather see the metronome feature and the "fast tuning" and the "okay to tune down" setting removed from the Roadie3 and have an "Open Ear" tunning feature that does not have to be logged in to the app in order to use it. Like an app, you would do/use on your cellphone but built into the Roadie3. That feature is there WHEN connected to the app. That would seem like a better solution for a fast tune. Turn it on, scroll down, click the OK arrow, set it down next to you, and watch the graph as you pluck and tune. Most guitars people buy nowadays have a built-in tuner, but not all do and not all are created equal. ---- This is just my opinion, I ain't nobody special. It seems to be pretty accurate. I have tested it against multiple tuners. The Roadie3 tuning seems to match perfectly with my Fishman built-in tuners. Expensive, yes. Cool, yes. Needed, meh. Awesome to have, yes! Should you buy one, definitely.

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.
