After updating to 4.0 and trying a whole bunch of rigs recently I've noticed it's not just me but also a few popular profiles that have an issue with clipping mainly with clean profiles.
I do pay close attention to this when profiling and I find even in general some sort of level meter would be a useful guide to determining levels withing the unit when profiling also for consistancy.
As a sound engineer i feel this is a critical but overlooked feature of the profiling procedure.
Also not sure if there is but a way to alter the level internally ( maybe a editing program Mac/PC) if the profile is clipping after the profile has been created.I find that quite often after making clean profiles with the Kemper impulse algorithm and even refining with no clipping during the process that I can still get clipping using that profile later with the same guitar.
If this program also have other tools such as phase detection and analise frequency response I'm sure it would help make better profiles.
My only gripe after having the unit over a year. It's one spectacular piece of work Kemper !
