I currently have an RP250 and this RP500 would make an awesome upgrade. I love the combo effects in the Digitech product line, but would be really sweet to be able to kick off one of them from time to time using the stomp-box-type buttons on this pedal box. I also appreciate being able to turn off the cabinet modeling for live performances, but still having them for studio use. The inclusion of Cubase LE is pretty nice too, I have to add...
