I just bought an Axe FX 3, pictures to follow. I investigated using stereo patches when I am running it in mono, and this is what google said: ". For best results, ensure your preset uses a mono Cabinet block, or set the Output 1 mode to "SUM L+R" in the I/O > Audio menu to combine stereo signals without losing sound. " I did this and configured the power amp **(Fryette) to run in mono. I am wondering how much loss of tone/sound/effect I will experience using patches made for stereo. Is it a significant loss? Will it vary by patch?
