Has anyone had any issues with the vast differences in volume control from one patch to another. I've only had mine for a week and I love the ease of use with my Bluetooth phone and the remote app. But, it seems that even if I try to adjust the volume of a patch, I'll go back later and it does not save my adjustments. I'm using the white and pink volume adjustments. It only seems to make a difference when you go into an amp to edit, adjust the volume, then save. Also, why is there no save option in the app? I have seen some L6 videos that show saving your edits. I do not have that feature. I have to save manually by using the footswitches, etc. Also...I would love to be able to incorporate my own amp's tone into the patches, and I have used the 4CM. But it does not seem to have much depth and I resort to using my wonderful amp as powered speaker for this thing. Thoughts anyone?
