Kemper Doesn't Sound Quite The Same When Tracking On My Daw...

I don't know how relevant this is but I use an RME Fireface UC and track post Stack without the efx section as I can provide better effects for the guitar using UAD or Plugin Alliance. I monitor the guitar direct through the mixer and not through the DAW. I do find that the sound in the DAW if I use the EFX section to be less present. I have always put that down to the way that efx affects the sound in a mix. The guitar sound is much easier to get right adding compression, eq, reverb and delay in the Daw.
