Jennman47, great slap-back setting. Thanks. And thanks for the other replies.
I stumbled upon a nice Pink Floydish (Run Like Hell/The Wall) type setting that I have been having fun with. It works well with double picking the low E string while working in lead licks at the same time. See if you like it:
Delay Time: 2:30
Delay Level: 12:30 (vary according to taste)
