Strange stomp behaviour: Compressor functions even when mix=0%

  • I have a rig set up inside a performance, which has a compressor stomp placed pre-stack. I have morphing set to switch mix from 0% to 100%. However, I notice that with the mix at 0% the compressor is still affecting the tone. If I switch the stomp off altogether there is an audible difference. I have not noticed this behaviour in any stomp effect before. Is this normal, and if not what's causing it?
