I can't figure this one out? All 3 of my Kuassa amp sims give me nothing but horrible feedback when added to the fx bin or PC. My levels are fine but as soon as added and and with the levels all way down they sound like a rabid monkey jabbing a toothpick in a garage sale Sears food blender.
 
I have zero problems with this same plugin in Studio One, Reaper and Live. I love this plugin for it's simplicity and unique tone and hate not being able to use it so any advice is more than welcome.
 
Thanks

This took me a while as I have spent hours trying to find the thread that gave me the answer when I had this problem (to no avail) so I experimented and found the cure myself!
When you create the sim in the FX bin it changes the Sonar track interleave to mono. You need to click on the "O" in the Console and that turns it into an overlapping "OO". Things will sound better after that.
 
Grum.

Grum has the answer! But you can also change the input at the top left to mono ( it may say left or right, not sure), though I just change the interleave button to stereo like Grum mentioned.
