Of course every headphone is EQ'd differently and every room has it's problems. But this doesn't matter here. I compared two reamped signals through the same monitor source(s).
I know this won;t help but....
- The Kempers E.Q. isn;t odd, you should not need to do any massive E.Q.ing - which leads me to suspect there is another issue in your signal chain
- You can get a great sound out of a Kemper for what you are doing.
There are so many factors at play its really difficult to diagnose. Reamping should have ruled out playing etc so now its in the monitoring and your set up.
