I do have an AXE 2 here so I took this opportunity to try some profiles. Since the beginning I thought that the high gain profiles have more hiss than expected. Some hiss is actually added when profiling.You cannot hear it at the time of profiling if you compare reference and Kemper amp because your amp is connected to the KPA input section so there's even more noise than when the profile is done.But if you want to hear it just unplug your amp in from the KPA send when you are ready to profile and listen..You'll hear quite some noise reduction.You'll also hear that the sound isn't the same if you plug your guitar direct in it . Unless my unit is defective which I doubt ...
This is kindda of expected..anything you put in front of a high gain amp will add noise except some high end buffers like Cornish.But I wonder if the input section could be made a little more silent and transparent ..Christoph ?
