The cool thing about this unit is that it's pretty straight forward. I worked in a music store for awhile and had time to play with this thing. It's good bang for the buck. No real tricks to it, just a straight forward processor. I used to have an RP20 which was the mothership of 1999. It's really cool, but now I prefer the sound of analog pedals. Do what you like best and you can't go wrong.
