my tuner is chromatic made of hardwood in america in 1992 ive dropped it at least a hundred times a year. it still works. my tibetian monk chant/ mongolian throat/didge voice is in E, i usually use this when i cant find the tuner. i dont like tuning forks the tune in my head overides the sound of the guitar. and i hate vibration on my tooth. i think euro car horns are G#.
I can tune my wife out by the sounds of her natural frequencyssss
