The amp models use different processing, so you will NOT get the Insane sound starting with the Clean setting, etc.
The models base their sounds on what the Line 6 people have analyzed for the basic sound characteristics of the amps in question.
Each of the four tones is based on a completley different amp, that is the difference. You cannot make them sound the same. We don't have the settings for the factory presets, but a reset would get them back for you.
