Overall, I am very pleased with the tuner. Only had it a few days, but the build quality seems very high.
Still looking at the 'sweetened' tunings. The 'GTR' setting seemed the same as 'EQU' to me - a couple of strings still needed a tweak for chords to sound really 'in'. I will look further into this and try it across several guitars.
I was disappointed to see that the two strobe 'wheels' are not independent. They might as well be one as they always move together. This is not like an old style strobe where the outer ring shows the required fine adjustment by still moving when the inner has stabilised. Nevertheless, it works.
The display is satisfyingly bright, but can be adjusted by choice of colour as some are not so bright, which may be suitable for some environments.
If I could suggest one improvement; don't put rubber on the base - leave it bare metal. Then supply three kinds of pre-cut stick-on base; BOTH types of 'Velcro' - rough AND smooth - plus the rubber one (as pre-installed). Then you will please everybody!
