Quick question - can I upload someone's free profile?

Originally, edited rigs were not posted, but newer users have been doing it for years.

So, If the original author name is still in the amp and cabinet, I don't see why you can't. My suggestion is to include your user name in the updated rig name, or rig comment field.

Ive done this a bunch. Technically its a violation of terms of service, but Kemper will look the other way so long as you have the original author's permission and arent overwriting tags for the authors name, which you cant do in Rig Manager. I even leave the rig name as unmodified as possible by append "MAB"
