I hear ya. I was just messing around with my DD-6 and my amph. I'm beginning to see Spud's point about the delay. Any difference in mode would probably be very subtle. Obviously cool, but worth ~$150? WRT the M5: right now I have my EX-7 and CF-7 which are mostly gathering dust. It's not because they are bad pedals. I just don't use those effects very frequently.
