I now have bought a used Line 6 POD GO. After using various Roland / Boss guitar processors for many years, I am very happy with the sound in POD GO. But I have a big problem. The harmonizer does not use the same scale as the Boss GT. Although there are many minor scales to choose from, none work for me as Boss GT did. The result is that some songs on the repertoire must be left out. To the best of my knowledge, the Boss GT has the "correct" minor scale. Does anybody know if there is any way to fix this?
