Topic: tuning issue
Trying to tune my made in China plywood classical guitar using this http://www.proguitartuner.com/guitar-tuner/ tuner with my laptop inbuilt mic. It has always worked nicely, but lately I seem to have a lot of trouble with the bottom strings, B in particular, it has gone really stubborn. When I get close enough to B, it starts to behave in an odd way. It starts off ringing as B for half a second or something and than jumps to F sharp (always exactly F sharp, never anything else). I am a bit on the tone deaf side and total noob, but it sounds weird even to my ear (it sounds, well, broken)
Could the problem just be in dead old strings? (they should be dead old from what I know about the history of the instrument, it's the one that goes around our church so everyone has fiddled around it but I guess no one has bothered to invest in new strings, neither have I) Or is it something natural? Or is it something bad?
