Yesterday, I was trying to profile my home amp (badcat the paw).
I tried to connect send1→amp input→amp speaker out→power attenuator (crews GBVI)amp input→attenuator line out→return1, but I couldn't get it to work, so I gave up. Today, I started the kemper stage and connected my guitar to the input to play. It sounds like it was plugged straight from the guitar into the audio line-in.
The input and output volume LEDs also light up green, so it's not clipping internally.
When I plugged the guitar into the amp, the sound came out fine, so there is no problem on the guitar side or the shield side, and I checked the clean sense and distortion sense, and they are set to 0.
What could be the cause? Could it be an internal problem?
