I just sold mine a few days ago. I used it in my POG2/Reverb/Delay loop. I used it to bring in my pad sound on command, and quickly fade in my clean signal when the bass line needed to start. You have a lot of control over how long the taper takes place. It is a fantastic tool for getting in and out of effects that you want to trail over your clean signal. I even kept my Ditto in the loop and brought loops in and out for one particular set. I only got rid of it because my Blue Sky took over that role in my playing.
