This tune is amazing and i have no faults with it, the screen is amazingly bright and always clear, perfect for gigs as well as high contrast screen, and when turned on the output is muted so can tune in silence, the only thing is some other tuners have two outputs one that mutes output when activated and one that leaves the output at all time, but i think this muting is best anyway, the tuning system is SO accurate, and so very easy to use as the lights start to turn from red to green gradually on the two blocks either side of in tune, so is very precise, well worth the money from those cheaper peddles with little LED lights
