Thanks lollipop, I actually meant the express pedal, not expression hence the comment about only 4 channels. I ended up buying a pre owned mk1 shortboard. However when I plug it in I get no backlight and the display only reads line 6, i get no lights and have only very basic function to switch between banks, channels and tuner. I will try a different cat5 cable just in case there is an issue with that first otherwise I'm worried I may have bought a dud unit. Not a great start!
