what amp(s) are we talking about?
have you tried reducing the volume of the amp?
have you refined the Profile?
The amps are Peavey Ultra + , Victory Kraken and an old Ampeg . On the Peavey i did a mod to bypass the internal noisegate , but the profiles are about 75% close to the source . The bass frequency pumps up every time when i refine the profile - i did a lot of different techniques , but nothing helped .When I profiled with a Lowcut n and 80 hertz , the profiles went into a thin and lifeless character .
