Been practicing with my Goodtime 2 lately. The last couple weeks played "in tune". Then all of a sudden, my 3rd string, even though the tuner shows it is in G, sounds very "off", for lack of a better description. I'm not quite understanding what is going on. If the tuner shows it is in G, then why all of a sudden does it not sound correct after practicing on and off for the past 2 years? Is there something I'm missing? Did my hearing change suddenly? Or is there something else i'm missing? Thank you.
