I just bought myself an Axe FX Ultra to compose and record some of the new stuff I am working. My rig is very simple, guitars into the Axe FX Ultra input using 1/4" cable and output through the unbalanced L & R into studio monitors. Few days into trying it, I just realized that only one of the monitors is producing the sound. I have tried flipping the L / R and the sound flipped as well, so it has to do with a setting inside ( I hope ! ). There is a similar thread below few years ago with a similar problem, but nobody has the solution for it yet ( Dealing with unbalanced stereo issue) Has anyone else experienced this issue and if there is a possible solution ?
