Why don't you just leave it at A440 and tune the fisrt string to E flat etc.?Dougvh04 said:Is 439 HZ a half step down from 440 HZ. I'm using a Korg tuner and trying to calibrate it inorder to tune down a 1/2 step. I'm just a beginner learning Social D and dont have the ear yet to do it manually. Any help would be appreciated!
