Thanks, I'll give it a try later today and report back with my findings - appreciate the help with this!
I continued experimenting - I switched to a different cable profile called "Cable Direct" by PWhe23 in Rig Exchange - after I matched volume levels between the on and off states of the amp module, the drive effects sounded essentially the same whether the amp was in or out of the signal chain. I'm guessing the earlier cable patch profile we were using (LMTTRAY - A-Stick) had some profiled qualities that reacted in unexpected ways when the drives were engaged. All good for me on this point.
I also re-installed the latest firmware, and continued to experiment with the various drive options via headphones and into a real amp - here are some preliminary findings:
- the Kemper Drives and Green Scream defaults still have more of that clean signal mixed in and give (me at least) a less familiar tone and feel, although as Christoph mentioned, this gets reduced somewhat as the drive and tone settings are turned up. Perhaps I just need to get more familiar with Kemper Drive options since the presets don't correspond with how I typically use these pedals. Personally, these tones don't feel or sound particularly "right" to me especially going into a real amp (and of course that could just be my own perceptions).
- For the most part, the drives outside of the Kemper Drive (e.g., Plus DS, One DS, Mouse, Full OC, etc.) have more of the expected feel - not sure if the firmware re-install had something to do with this, but there seems to be an improvement going into the amp which makes me a bit more optimistic. I will continue to experiment, but it feels like I'm moving in the right direction.
I'll continue to report back as I learn more - huge thanks to everyone that's been following along, and for sharing thoughts to help me work this out, I greatly appreciate it.
Best,
Dango
