hi again . this is my 2nd q :
sometimes when I'm trying to tune up the 2nd string , the tuner in guitar mode shows 7B ( instead of 2B ) and in chromatic mode shows B2 ( instead of B3 ) . I have the same problem with 1st string . the guitar mode shows 6E ( instead of 1E ) and the chromatic mode shows E2 ( instead of E4 ) ! what shall I do then ? loosening the string ? tightening the string ? what's the problem ?
