Effects

I've heard about the digitech RP50, is that what I should go for if I was to purchase an effects box/pedal????

Check out my Boss GT-3 comments in the Tone and Effects>Pedals response #27. Very few of these options are available to you with the RP80. There is however a difference in price.
I once thought a "Sweeping Arpeggio" was an Italian janitor.
