I heard a lot of people "complaining" that they bought profiles from commercial sellers but that those profiles doesn't sound the same as in their demos.
And that is very true!
But the truth is, they do sound the same if the demo clips has no post processing on them!
What makes the biggest difference is your playing!
One of THE MAIN reasons is your right hand, the way you palm mute, pick the strings!
In this clip you can hear 3 different players on the same guitar, with the same pickup and the same pick straight into the same Kemper profile.
EDIT: The guitar used in this clip is Schecter BlackJack Solo with Seymour Duncan SH5 pickup.
So, there's simply NOTHING wrong with your Kemper when you start demoing profiles you bought while expecting them to sound 100% identical like in demo clips.
What you think?
In most cases, Soundcloud uses a bandwidth of only 128 kbps. As a result, what you hear isn't free of artefacts, especially the high end. For critical listening and also product comparison, please keep that in mind. Users who setup a comparison should use linear wave files and supply dropbox links.
If you hadn't said they use the same stuff I would believe they used different profiles. The first sounds darker, the second slightly more treble, or presence, and the third slightly more bright.
