Here is my signal chain:
Kemper main OUT ---> BigSky ---> mixer
With the Kemper main volume at max (0.0dB), the BigSky clips pretty hard. If I put the BigSky in an FX loop block on the Kemper, there is no clipping. I don't think the BigSky can handle line level volumes, despite what the Strymon FAQ says about it being able to handle +8dBu and line levels.
I'm using the Kemper for the amps, and using a pedalboard. I want to be able to switch different amps but not have to program the FX loop block in every time.
By the way, the Strymon Volante does NOT have this problem:
Kemper main OUT ---> Volante ---> mixer
works just fine, even when the Kemper is at max volume. So the clipping seems to be a BigSky problem. I could just turn the Kemper volume down, but I'd lose quite a bit of volume (~15dB or so) just so the BigSky doesn't clip. Is anybody else running a similar setup with the Kemper just running amp sounds and then running the out to a pedalboard? How did you solve this problem?
