Question:

"ghanshyam asks "Hello, I am a complete beginner at this so go easy on me. I have an electric guitar, and electronic tunning tool (where you plug the 120mm jack from the guitar into the tuner). When I am tunning what frequency should I use? Do I use the default 440 frequency for all strings? Thank You""
