Very easy to use and just amazing sounds.  After setting it up with my rig, I spend a couple hours just monkeying around with it.  I'm not Hendrix, but this pedal gives some hope.  Both my kids came in the room and watched me play, mesmerized at the goofy things I was trying.  The wife came, stood in the doorway, sighed and shook her head.  This is awesome and so much fun.
