Do you mean your in ear or on stage sound?
Sometimes it helps to ask the sound engineer, if he can do a little eq stuff on in ear mix to get better sound.
And leveling the instruments and try to get your sounds as loud as possible.
What I found out for me, using the same equipment (headset) at home and live. That you don't have a other feeling of the sound live.
Or do you mean in the FOH mix?
Maybe ask the sound engineer for feedback, what you can do better.
Iam a very happy kemper stage live user.
