Hey there, folks - I have a really annoying problem that I can't figure out.
I'm using my Mesa/Boogie Mark V high-gain profile and I'm using my live rig pedalboard. I'm getting an intolerable high-pitched squeal/feedback that kicks in the SECOND I turn on my compressor or my OD before the kemper, OR if I turn on the OD in the Kemper. I have this problem even with no pedals active and the guitar turned down completely, loop disengaged.
I got a similar problem (not exactly the same) when I was profiling using my Mesa Cab Clone, but hitting the ground lift eliminated it. None of the ground buttons on the Kemper have any effect in this case. And as soon as I turn off any additional gain stages, the problem disappears. I can have the Kempers Tube Screamer on, but if any of the setting are anything more than "0.0," I get the squeal.
I'm really unsure of what could be causing this very unmusical feedback/squeal. It doesn't make sense that I can crank the amp's gain with no issue, but the second I add an OD, it goes bananas. Anyone else have this issue? How did you solve it? I don't believe I had this issue until the most recent update, if that makes any difference...
EDIT: It DOES actually feedback when the amp's gain is turned up, but it will squeal regardless of the output volume. Still very frustrated...
