This is a very new guitar tuner concept for me. I am simply learning about it and trying it on my guitars for now. I am very interested in the sweetened tunings available and looking forward to spending time on that process.
If I knew more about this thing I would have given it a 5 star review. I’m sure it will be fine. Cheers.

One of the best tuners I’ve ever owned. Much more concise than a Snark.

Absolutely the best tuner ive ever had! Most accurate easy to use and with the HDC being rechargeable ill never use another kind of tuner again! You guys are the absolute best at what you do!

Just want to point out that more sweeteners can be added besides the factory ones and that the support team was very helpful in guiding me, even sharing the one I specifically needed (TT7). Top notch!

Wish it could identify all simultaneously like polytune and chords

I have been playing and recording since the 1970s. This is the best, easiest, most accurate tuner I have used, in all that time.

The biggest update for the HDC is the stability of the strobe during tuning, and the accuracy. I've never heard my guitars of basses so precisely in tune, except for lucky ear tuning :)
