Am I the only one who finds ducking delay is a cool effect, but hard to get right? It's one thing to set up at home or in studio, but really tricky to use in a jam or live sitch. You have to get the input sensitivity, threshold, and effect levels all just right...though when you do it's a cool effect for certain styles. It's tricky enough to get FX levels right ANYWAY unless you are setting them up at gig volume, and even then it can depend on the dynamics of the room how much you hear delay, reverb, etc. On a modeler the access to ducking parameters is too cumbersome to tweak on the fly.
