So, I tuned my 5er tonight with it. Tried to tune B, E, A, D, G. Very simple right? Wrong. The Boss seems to be 1/2 step off for the B and E string, but fine (very close anyway) for the rest. I checked it against another tuner, and of course my trusty ears, and all I can say is, ***? I always have it set to display the name of the note, never "bass" or "guitar" or whatever else it says on there. Is there a way to "reset" these things, or is mine just toast? thanks!
