Completely honest review, from frustrated low tuning guitar player :)
I am extremely positively suprised how accurate and fast this tuner is. Especially with tuning drop tunings (standard A tuning and drop G). On standard guitar tunings, it's extremely precise, up to 1 cent precision. On low A string I managed to get precision within +-2 cent difference. To be honest, it's almost impossible to get more precise than that with low tuned guitars. Harmonics also very easy to measure.
Has multiple modes, both needle and strobe tuner (bare in mind, this is not a strobe tuner, but it can act like one), and hybrid modes in between, kind of combination of both worlds. One that I use the most is these hybrid combos, as I like strobe tuners a lot!
Quality wise, a pedal is tough and really well built, for heavy duty guitarists. Lighting on the pedal is amazing, it shows very clear from different angles. Light is also very bright and nice to see on stage. Fits within pedal boards very nice. I haven't used yet cable power management, but I do not doubt it works just as fine.
Finally, I have found a really precise tuner for the not insane amount of money! I recommend this to anyone who was having troubles with tunings, especially in studio work! Never get out of tune again ;)
